Let S = the selling price

The dealer ... set the selling price equal to purchasing price ($150) plus a markup that was 40% of selling price.
So, the markup = 0.4S
In other words: S = 150 + 0.4S
Subtract 0.4S from both sides to get: 0.6S = 150
Solve: S = 250
In other words, the selling price was $250

What was the dealer's gross profit from the purchase and the sale of the desk?
The profit = $250 - $150 = $100

Answer: E
