A new, larger tube of lotion contains 15.6 ounces The new bottle says you get 30% more than the amount in the original tube.How many ounces were in the original tube?

the original tube contained 12 ounces.

Step-by-step explanation:

Let x represent the number of ounces of lotion that was in the original tube.

The new bottle says you get 30% more than the amount in the original tube. The number of ounces of lotion that makes 30% is

30/100 × x = 0.3 × x = 0.3x

The new, larger tube of lotion contains 15.6 ounces. This means that the number of ounces of lotion in the new tube is expressed as

x + 0.3x = 15.6

1.3x = 15.6

x = 15.6/1.3

x = 12
