Answer: 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
Answer: original tube contains 10.92 ounces
Step-by-step explanation:
The new larger tube has 15.6 ounces which is 30% more that the original tube.
Then the original tube contains
15.6 x 30% = 4.68
Therefore the original tube contain 15.60 - 4.68 = 10.92 ounces
