q quarters, L loonies.
R is how many dollars per loonie.


system%28q=2L%2C+0.25q%2BRL=12.50%29

0.25%282L%29%2BRL=12.50
0.5L%2BRL=12.5
L%28R%2B1%2F2%29=12%261%2F2
2LR%2B1=25
2LR=24
LR=12
The question is really about quarters.
2LR=24
qR=24
q=24%2FR

Try choosing R from whole number factors of 24, and test in the money count equation to see which values for R work and which do not work.
