30.A furniture dealer purchased a desk for $150 and then set the selling price equal to the purchase price plus a markup that was 40 percent of the selling price. If the dealer sold the desk at the selling price, what was the amount of the dealer's gross profit from the purchase and the sale of the desk?

(A) $40
(B) $60
(C) $80
(D) $90
(E) $100

請問一下喔…為何答案是）（Ｅ）
而不是 [150*(1.4)]-150=60呢

題目是說markup的部份是"售價的40%"哦!!, 您設的方程式會變成是"進價的40%", 正確的方程式應該是設售價為X, 方程式為150+40%X=X, X=250, Gross Profit=250-150=100!!
