Problem: Harvey has 70 roller skates in his shop. If 42 of those roller skates are for children, how many roller skates does Harvey have for adults?
GPT-4o:
To determine how many roller skates Harvey has for adults, we need to subtract the number of roller skates for children from the total number of roller skates. Given: - Total roller skates = 70 - Roller skates for children = 42 We calculate the number of roller skates for adults as follows: \[ \text{Roller skates for adults} = \text{Total roller skates} - \text{Roller skates for children} \] \[ \text{Roller skates for adults} = 70 - 42 \] \[ \text{Roller skates for adults} = 28 \] ### Answer: 28

Problem: In a ballet school, there are 32 children practicing for an event. Then a few more children join the practice. Now, they total 48 ballerinas. How many new children joined the practice?
GPT-4o:
To determine how many new children joined the practice, we need to find the difference between the total number of ballerinas after the new children joined and the original number of children. Initially, there were 32 children practicing. After a few more children joined, the total number of ballerinas became 48. We can set up the equation: \[ \text{Number of new children} = \text{Total number of ballerinas} - \text{Original number of children} \] Substituting the given values: \[ \text{Number of new children} = 48 - 32 \] Performing the subtraction: \[ \text{Number of new children} = 16 \] ### Answer: 16

Problem: A teacher initially had 'a' sheets of special star stickers in her drawer. She then used 60 stickers for rewarding her students in class, and now she has only 2 sheets left. How many sheets of star stickers did the teacher initially have in her drawer?
GPT-4o:
Let's denote the number of sheets of star stickers the teacher initially had as \( a \). Given: - The teacher used 60 stickers. - After using the stickers, she has 2 sheets left. We need to find the initial number of sheets, \( a \). First, we need to understand that the teacher used \( a - 2 \) sheets of stickers, since she has 2 sheets left. Since each sheet contains a certain number of stickers, let's denote the number of stickers per sheet as \( s \). The total number of stickers used is given by: \[ (a - 2) \times s = 60 \] To find \( a \), we need to know the number of stickers per sheet, \( s \). However, since \( s \) is not provided, we can only express \( a \) in terms of \( s \). Rearranging the equation to solve for \( a \): \[ a - 2 = \frac{60}{s} \] \[ a = \frac{60}{s} + 2 \] Thus, the initial number of sheets \( a \) is: \[ a = \frac{60}{s} + 2 \] Without the value of \( s \), we cannot determine a specific numerical value for \( a \). Therefore, the answer is expressed in terms of \( s \). ### Answer: \(\frac{60}{s} + 2\)

Problem: Fahim went to a home decor store and bought some towels. If he bought 7 towels first, and the total towels he has now is 58, how many towels did Fahim buy in his subsequent visits to the store?
GPT-4o:
To determine how many towels Fahim bought in his subsequent visits to the store, we need to subtract the number of towels he initially bought from the total number of towels he has now. Fahim initially bought 7 towels. The total number of towels he has now is 58. Let's denote the number of towels Fahim bought in his subsequent visits as \( x \). The equation to solve is: \[ 7 + x = 58 \] Subtract 7 from both sides to isolate \( x \): \[ x = 58 - 7 \] \[ x = 51 \] Therefore, Fahim bought 51 towels in his subsequent visits to the store. ### Answer: 51

Problem: A backpack originally had 3 items inside. Later, an additional 69 items were added in. If a total of 72 items are now in the backpack, how many items were initially in the backpack?
GPT-4o:
To determine how many items were initially in the backpack, we need to subtract the number of items added later from the total number of items currently in the backpack. Given: - Total items now in the backpack: 72 - Items added later: 69 We can set up the equation: \[ \text{Initial items} + \text{Items added} = \text{Total items} \] Let \( x \) be the initial number of items in the backpack. Then: \[ x + 69 = 72 \] To find \( x \), we subtract 69 from both sides of the equation: \[ x = 72 - 69 \] \[ x = 3 \] Thus, the initial number of items in the backpack was 3. ### Answer: 3

Problem: A farmer has an unknown number of cows in his field. When he sells 39 of his cows, he is left with 55 cows. How many cows did the farmer have to start with?
GPT-4o:
To determine the initial number of cows the farmer had, we need to add the number of cows he sold to the number of cows he has left. Let's denote the initial number of cows as \( x \). According to the problem: \[ x - 39 = 55 \] To find \( x \), we add 39 to both sides of the equation: \[ x - 39 + 39 = 55 + 39 \] \[ x = 94 \] So, the farmer initially had 94 cows. ### Answer: 94
Expected answer: 94

Problem: The wind speed dropped from a certain level to 29 mph and it was noticed that this was a decrease of 35 mph. What was the wind speed before it started to decrease?
GPT-4o:
To find the wind speed before it started to decrease, we need to add the decrease in wind speed to the final wind speed. Given: - Final wind speed = 29 mph - Decrease in wind speed = 35 mph Let the initial wind speed be \( x \). The relationship can be expressed as: \[ x - 35 = 29 \] To find \( x \), we add 35 to both sides of the equation: \[ x = 29 + 35 \] \[ x = 64 \] ### Answer: 64 mph

Problem: The zoo started the day with some number of animals, which we'll call s. During the day, 24 animals were moved to a separate area of the zoo for cleaning and care. After this, there were still 75 animals visible to visitors in the main section of the zoo. How many animals were there in total at the zoo at the start of the day?
GPT-4o:
To determine the total number of animals at the zoo at the start of the day, we need to account for both the animals that were moved and the animals that remained visible to visitors. Let's denote the total number of animals at the start of the day as \( s \). According to the problem: - 24 animals were moved to a separate area. - 75 animals remained visible to visitors. This means that the total number of animals at the start of the day is the sum of the animals that were moved and the animals that remained visible. So, we can write the equation: \[ s = 75 + 24 \] Now, we solve for \( s \): \[ s = 99 \] ### Answer: 99

Problem: A tube of toothpaste usually lasts you for 9 weeks. Now, you've noticed that your current tube has lasted for 61 weeks already. For how many weeks has your tube of toothpaste surpassed its usual duration?
GPT-4o:
To determine how many weeks the current tube of toothpaste has surpassed its usual duration, we need to subtract the usual duration from the current duration. The usual duration of a tube of toothpaste is 9 weeks. The current duration of the tube of toothpaste is 61 weeks. We calculate the difference: \[ 61 \text{ weeks} - 9 \text{ weeks} = 52 \text{ weeks} \] ### Answer: 52 weeks

Problem: In a box, there are 79 triangles. Overall, if there are 93 shapes in the box, how many shapes are not triangles?
GPT-4o:
To determine how many shapes are not triangles, we need to subtract the number of triangles from the total number of shapes. Given: - Total number of shapes = 93 - Number of triangles = 79 We calculate the number of shapes that are not triangles as follows: \[ \text{Number of shapes not triangles} = \text{Total number of shapes} - \text{Number of triangles} \] \[ \text{Number of shapes not triangles} = 93 - 79 \] \[ \text{Number of shapes not triangles} = 14 \] ### Answer: 14
Expected answer: 14
Correct? Yes
Problem: A roller skating rink had 44 pairs of roller skates. After purchasing several new pairs, it now has 71 pairs. How many new pairs of roller skates did the rink buy?
GPT-4o:
To determine how many new pairs of roller skates the rink bought, we need to find the difference between the current number of pairs and the original number of pairs. The original number of pairs of roller skates was 44. The current number of pairs of roller skates is 71. We subtract the original number from the current number: \[ 71 - 44 = 27 \] Therefore, the rink bought 27 new pairs of roller skates. ### Answer: 27
Expected answer: 27
