A departmental store charges the commission of 15 percent on the first sale of items worth $50,000 and then an additional 10 percent on any sale price that exceeds the initial $50,000. If the department store earned $20,000 in commissions for the sale of a series of diamonds, what was the sale price of the diamond set? Choose one:
A) $215,000 B) $365,000 C) $115,000 D) $175,000 E) $160,000
20,000 = 0.15 *(50000) + 0.10 (x - 50000)   20000 - 7500 = 0.10 (x-50000)   125000 = x - 50000   x = 1,75,000   Answer : $175,000
