Question

At the green house of salad, you get a $1 coupon of every 3 salads you buy. What is the least number of salads you could buy to get $10 in coupon?

Answer 1

Proportion: $1 coupon / 3 salads = $10 in coupons / x salads

Solving proportion:

1/3 = 10/x

30 = x

x = 30 salads

You would need to buy 30 salads to get $10 in coupons.

Hope this helps!! :)
