Question

A roll of carpet that contains 250 yd of carpet will cover how many rooms if each room requires 7 3/4 yards of carpet?

Answer 1

Answer: 32 room

Explanation:

`7(3)/(4) =(4(7)+3)/(4) =(28+3)/(4) =(31)/(4)=7.75`

If 1 room = 7.75 yd of carpet ⇒ x rooms = 250 yd of carpet

Use proportions & cross-multiply to solve:

`(1)/(7.75) =(x)/(250)\\7.75x=250\\x=(250)/(7.75) =32.258`

So 250 yd of carpet can cover about 32 rooms.
