Question

Bari Jay, a gown manufacturer, received an order for 700 prom dresses from China. Her cost is $30 a gown. If her markup based on selling price is 72%, what is the selling price of each gown? (Round your answer to the nearest cent.)

Answer 1

You must first determine the cost for her to make 700 gowns at $30. Next you want to take that number and divide it by .72 to determine what the increased total for all 700 gowns would be finally you divide by 700 to get the price per unit.

Your equation should look something like this:

(30*700)/.72/700
