An automobile parts supplier charges $25 per package of gaskets. When a customer orders more than 10 packages of gaskets, the supplier charges 4/5 the price for each package in excess of 10. During a certain week, the supplier sold 60 packages of gaskets. If 25 percent of the gaskets went to Company X, 15 percent to Company Y, and the rest to Company Z, what was the total amount, in dollars, that the parts supplier received in payment for the gaskets?  Answers.
A) 1305
B) 1545
C) 1375
D) 1345
E) 1455

Rationale: "$ 25 per packet of gasket in case a customer orders less than 10 in case a customer orders > 10 price per gasket = 25 * 4 / 5 = 20 a certain week the supplier sold 60 gasket 1 . he sold 25 % of the gaskets to x = 15 gaskets = 25 * 10 + 20 * 5 = 250 + 100 = 350 2 . he sold 15 % of the gaskets to y = 9 gaskets = 25 * 9 = 225 3 . he sold remaining 60 % to z = 36 gaskets = 25 * 10 = 250 + 20 * 26 = 770 thus , total money earned 350 + 225 + 770 = 1345 answer is d"
