Question

In a bag of gum balls, 30% of the gum balls are blue. There are 12 blue gum balls in the bag. How many total gum balls are in the bag?

Answer 1

64

Explanation:

Answer 2

40

Explanation:

Since 30% of the bag is blue, you can setup the equation,
`(3)/(10)x=12` where x is the total number of gumballs in the bag because that is what you are looking for. Simplify and you get
`x=40`. Checking this you get
`12=12` which is true.
