Brownsville, Texas, boasts being the southernmost international seaport and the largest city in the lower Rio Grande Valley. Ben Supple, an importer in Brownsville, has just received a shipment of Peruvian opals that he is pricing for sale. He paid $150 for the shipment. If he wants a 75% markup, calculate the selling price based on selling price. Then calculate the selling price based on cost. (again please show all work)

Let the selling price be S. The selling price based on selling price is found from:
[tex]\frac{S-150}{S}=\frac{0.75}{1}[/tex]
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:
[tex]\frac{S-150}{S}=\frac{0.75}{1}[/tex]
Cross-multiplying, we get:
112.50 = S -150
which when solved for S gives a selling price = $262.50.
