Pucks

The coach went to buy balls and pucks for his charges. He paid CZK 1,464 for 21 balls and 30 pucks. But then he found out that this amount would not be enough for him, so the next day he bought 9 balls and 10 pucks for 536 CZK. How much did 1 ball cost and how much did 1 puck cost?

Correct answer:

m =  24
p =  32

Step-by-step explanation:


21m+30p=1464
9m+10p=536

21•m+30•p=1464
9•m+10•p=536

21m+30p = 1464
9m+10p = 536

m = 24
p = 32
