Question

Manuel bought 9 pounds of apples. He has eaten three fourths

Answer 1

1. So, since Manuel bought 9 pounds and ate 3/4 of 1 pound, he has 8.25 pounds left  (9  - 0.75  = 8.25)

2. Let us call "x" the cost of 1 pound of apples

3. (8.25) * (x) = $15

4. x = $1.81818  rounded to the nearest dollar is $2 / pound
