Question

A music store buys compact discs for $12 each and sells them for $15 each. What is the percent of markup on these compact discs?

Answer 1

The markup on the cost price is
\[\frac{15-12}{12}\times100=?\ percent\]

Answer 2

You subtract the cost price ($12) from the selling price ($15) as follows:
15 - 12 = ? ..............(1)
Then you divide the result of (1) by the cost price ($12)
\[\frac{?}{12}=?\ ?............(2)\]
Then multiply the result of (2) by 100 to find the percentage.
