A 3-yard roll of aluminum foil costs $1.71. What is the price per foot?

.19 ¢

Step-by-step explanation:

1.) Multiply

There are 3 feet in one yard. And there are 3 yards. So,

3 x 3 = 9

2.) Divide

1.71 ÷ 9 = .19

3.) Check answer

.19 x 9 = 1.71

So it cost .19¢ per foot.

Hope this helps you out : )

idk sry

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
