A. A hockey coach bought 20 pucks for a total cost of $47.50. The pucks used for practice cost $2.00 each, and the pucks used for games cost $2.75 each. Write a linear system to model this situation:

b. How many of each type of puck did the coach purchase?
Practice pucks: Game pucks:

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
