Question

Joanna has 3 more books in her backpack than Sophie. If Sophie has n books, how many does Joanna have?​

Answer 1

n+3

Explanation:

We can combine the same letters, but not with numbers. If I said Sophie has 8 books, you'd say Joanna has 8 + 3 = 11 books. Joanna instead has n + 3 books. That's your final answer.

Answer 2

If Sophie has n books, then Joanna has n + 3 books since she has 3 more books than Sophie.
