Question

A factory made 46 jars of creamy peanut butter and 529 jars of chunky peanut butter. What percentage

of the jars of peanut butter were creamy?
Write your answer using a percent sign (%).

Answer 1

To solve this, write down what we know already.

46=creamy pb
529=chunky pb.

To set the equation up, we need to use the following formula:

a p
— = —
b 100

a Represents the value of which you need to find the percentage of. b Represents the whole number. In order to find the value that is equal to 100(%), we add 529 and 46 together, since we want to know the whole number, which is equal to 575. Using the formula from above, replace the variables with the numbers we know already. Your new equation will look like this:

46 p
— = —
575 100

The final steps are to cross multiply: (46)(100)=575p

4600=575p

Then divide to isolate the variable. You should get 8.


8% OF ALL PB JARS ARE CREAMY
