No. of products to \(X = 20\%\) of \(60 =12\)
No. of products to \(Y = 15\%\) of \(60 = 9\)
No. of products to \(Z = 39\)

Dollars form \(X = 10\cdot25 + 2\cdot \dfrac{4}{5}\cdot 25 = 290\)
Dollars from \(Y = 9 \cdot 25= 225\)
Dollars from \(Z = 10\cdot 25+29\cdot \dfrac{4}{5}\cdot 25 = 830\)

Total dollars \(= 290+225+830=1345\)

Therefore, B

Answer: B

Solution:

We see that Company X received 60 x 0.2 = 12 packages of gaskets, Company Y 60 x 0.15 = 9 packages, and Company Z 60 - 12 - 9 = 39 packages. Since both companies X and Z ordered more than 10 packages, each package in excess of 10 was charged 25 x 4/5 = $20. Therefore, the total amount of money the supplier received from the three companies is:

(25 x 10 + 20 x 2) + (25 x 9) + (25 x 10 + 20 x 29)

290 + 225 + 830 = $1345
