Question

One pound of candies costs $3.50.

How many pound of candies can be bought for $7?

How did you do it?

Answer 1

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!!

Answer 2

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
