Question 1017656: Jon has 12 5cent more than 25cent. His total is 9$ howmuch 5cent coins does jon have?

n = number of 5 cent coins
q = number of 25 cent coins
n = q + 12
5n + 25q = 900
Plug in the first equation into the second.
5(q + 12) + 25q = 900
5q + 60 + 25q = 900
30q = 840
q = 28
Jon has 28 25-cent coins and 40 5-cent coins.
