Answer:
I think you are asking for the price Robert paid after the 30% off. There are two ways to do this. The first way is to find 30% of the full price and substract it from the full price or we could find 70% of the full price.
Lets make x the new price.
Step-by-step explanation:
First way:
x = 79.95 - (79.95 x 0.30)
x = 79.95 - 23.985
x = 55.965
(we round to the hundredth)
x = 55.97
Second way:
x = 79.95 x 0.70
x = 55.965
(we round to the hundredth)
x = 55.97
