Part 1
A music store bought a CD set at a cost of ​$10. When the store sold the CD​ set, the percent markup was ​%30
. Find the selling price.

1 answer

To find the selling price, we need to calculate the percent markup based on the cost of the CD set and add that markup to the cost.

Markup = (Percent Markup / 100) * Cost
Markup = (30 / 100) * $10
Markup = $3

Selling Price = Cost + Markup
Selling Price = $10 + $3
Selling Price = $13

Therefore, the selling price of the CD set is $13.
