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 20 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?

A. 1305
B. 1345
C. 1375
D. 1415
E. 1455

Number of Gaskets sold to

Company X = \(\frac{1}{5} * 60 = 12\)
Company Y = \(\frac{15}{100} * 60 = 9\)
Company Z = \(60 - (12+9) = 39\)

Total Price = Price Charge to Company X + Company Y + Company Z
\(= (10*25 + 20*2 ) + (9*25) + (10*25 + 29*20)
= (25 (10+9+10) + 20 (2+29))\)
\(= 25 * 29 + 20 * 31
= 725 + 620
=1345\)

Ans: B
