Let the selling price be S. The selling price based on selling price is found from:
![\frac{S-150}{S}=\frac{0.75}{1}](https://tex.z-dn.net/?f=%5Cfrac%7BS-150%7D%7BS%7D%3D%5Cfrac%7B0.75%7D%7B1%7D)
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:
![\frac{S-150}{S}=\frac{0.75}{1}](https://tex.z-dn.net/?f=%5Cfrac%7BS-150%7D%7BS%7D%3D%5Cfrac%7B0.75%7D%7B1%7D)
Cross-multiplying, we get:
112.50 = S -150
which when solved for S gives a selling price = $262.50.
