Studdy Solution
Set up the equation to find the number of books needed for 3 coupons.
If 4 books give you 1 coupon, then for 3 coupons, you need:
4 books/coupon×3 coupons=12 books 4 \text{ books/coupon} \times 3 \text{ coupons} = 12 \text{ books}
The least number of books you could buy to get \$15 in coupons is:
12 books\boxed{12 \text{ books}}
