Question

How many free books did Larry get?
free books

Answer 1

For every 7 books purchased, Larry gets 2 free books. Larry purchased 21 books.

First, we find out how many sets of 7 books Larry purchased:

\[ \frac{21}{7} = 3 \]

Since Larry bought 3 sets of 7 books, he will get:

\[ 3 \times 2 = 6 \text{ free books} \]

Thus, Larry received 6 free books.
