q=number of quarters
d=number of times

1q=25 cents
1d=10 cents
total is 1620 cents
25q+10d=1620
divide both sides by 5 to simplify
5q+2d=324

also
5 times as many quarters as dimes
q=5d

sub 5d for q

5(5d)+2d=324
25d+2d=324
27d=324
divide both sides by 27
d=12
sub

q=5d
q=5(12)
q=60

60 quarters
12 dimes
