in one month a school recycled two fifths of its paper and produced 25 pounds of paper. how many pounds were not recycled

Question

math problem

Answer 1

p represents the pounds of paper

 

(2/5)p = 25         multiply both sides by 5

2p = 125             divide both sides by 2

p = 62.5             subtract 25 from both sides

p - 25 = 37.5

 

Thirty-seven and one-half pounds were not recycled.
