Problem: Harris found 7 books in his backpack. If the total number of books he has is 10, how many books did he originally have in his backpack?

GPT-4o:

To determine how many books Harris originally had in his backpack, we need to consider the total number of books he has and the number of books he found in his backpack.

Given:
- Total number of books Harris has: 10
- Number of books he found in his backpack: 7

The number of books Harris originally had in his backpack is the total number of books minus the number of books he found in his backpack.

Let's calculate it:
\[ \text{Original number of books in backpack} = \text{Total number of books} - \text{Books found in backpack} \]
\[ \text{Original number of books in backpack} = 10 - 7 \]
\[ \text{Original number of books in backpack} = 3 \]

GPT-4o:

To determine how many dolphins the trainer acquired, we start with the initial number of dolphins and the final total number of dolphins.

The trainer initially has 9 dolphins. After acquiring additional dolphins, the total number of dolphins becomes 10.

Let \( x \) be the number of dolphins the trainer acquired. We can set up the following equation:
\[ 9 + x = 10 \]

To solve for \( x \), we subtract 9 from both sides of the equation:
\[ x = 10 - 9 \]
\[ x = 1 \]

Therefore, the trainer acquired 1 additional dolphin.
