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?

iren [92.7K]

Answer: 32 room

Step-by-step explanation:

$7\frac{3}{4} =\frac{4(7)+3}{4} =\frac{28+3}{4} =\frac{31}{4}=7.75$

<u>If 1 room = 7.75 yd of carpet ⇒ x rooms = 250 yd of carpet</u>

Use proportions & cross-multiply to solve:

$\frac{1}{7.75} =\frac{x}{250}\\7.75x=250\\x=\frac{250}{7.75} =32.258$

So 250 yd of carpet can cover about 32 rooms.
