Today, everything at a store is on sale. The store offers a 20% discount. If the regular price of an item is x dollars, what is the discount price in dollars?

Question

im confused because i learned this but the method dosent apply to this type of problem in spicific

Answer 1

The discount price would be amount you would pay after receiving the 20% savings. If the regular price is represented with the variable x, then the amount left to pay after "taking off" the 20% would be 80% of the regular price. This could be written as 0.80x

As an example, let's say that a candy cost $2.00 as a regular price. Then assume that it is on sale for 20% off. You would save : 0.20 * $2.00 = $0.40

The amount left to pay (discount price) would then be $1.60

0.80 * $2.00 = $1.60
