A department store buys 200 shirts at a cost of $5,400 and sells them at a selling price of $30 each. Find the percent markup.

$31.85 so the nearest hundredth$31.90?

Step-by-step explanation:

Let the selling price be S. The selling price based on selling price is found from:

Cross-multiplying, we get:
0.75S  = S - 150
which when solved for S gives a selling price = $600.

To find the selling price based on cost, the following equation applies:

Cross-multiplying, we get:
112.50 = S -150
which when solved for S gives a selling price = $262.50.
