Question

In a candy factory, nutty chocolate bars contain 22.0% by mass pecans. If 5 kg of pecans were used for candy last Tuesday, how many pounds of nutty chocolate bars were made?

Answer 1

22% by mass pecans of a nutty chocolate bar.

This means that if a nutty chocolate bar is 100 kg, then it is made up of 22 kg of pecans.

(100 kg chocolate bar/22 kg pecan) * 5 kg pecan * 2.2 pound/1 kg = 50 pounds of nutty chocolate bar.

50 pounds of nutty chocolate bars were made last Tuesday.

Answer 2

Let's say that the total amount, in pounds, of nutty chocolate bars is "x"

So, if 5 kg is 22%, then 5/x = 0.22
So, all we have to do now is rearrange the equation to get x = 5/0.22 = 22.73 kg
1 kg is approximately 2.2 pounds, so we multiply 22.73 by 2.2 to get an answer of 50 lbs
