Cost price $8.50 What is the mark up at 27%

The cost after the mark up is $10.80

Step-by-step explanation:

In order to find the cost after make up, we first try to find the price of the mark up. To do that, we multiply the cost by the percentage (remember to turn it into a decimal first).

$8.50 *.27 = $2.30

Now that we have this, we add the mark up to the original cost to get the new marked up cost.

$8.50 + $2.30 = $10.80
