You can set up a proportion to answer this question.


(1)/(3.5) =(x)/(7)

This says, "If one pound costs $3.50, how many pounds is $7?"


Solve for x by cross multiplying.

7=3.5x

*Divide both sides by 3.5*

2=x


2 pounds of candies can be bought for $7.


Hope this helps!!

1 pound costs $3.50
x pounds cost $7

x = (7 * 1)/(3.50) = 2
so you can buy 2 pounds of candies for $7
