Question from toya, a student:

The cost for an item is $\$27.99.$ If the selling price is $\$39.99,$ then determine the following markup, %markup on cost, %markup on selling price

Hi Toya,

The markup is $\$39.99 - \$27.99 = \$12.00.$

What is $\$12.00$ as a fraction of the cost $\$27.99?$ Express this as a percentage.

Repeat for the selling price.
