Question

You work in a department store and sell a dress that is on sale for $58.80. If the regular price of the dress is $98, what is the discount?

Answer 1

The discount is 60%

Explanation:

We can set up a proportion to solve for the discount percent. On the left I will put costs in dollars and on the right the percentage of the cost, with the regular price on the top.

-> Percents are divided by 100 to become decimals

[Start]

`(98)/(58.8)=(1)/(x)`

[Cross-multiply]

98 * x = 1 * 58.8

98x = 58.8

[Divide both sides of the equation by 98]

x = 0.6

[Multiply both sides of the equation by 100 to get a percent]

The discount is 60%
