Question 974707
q quarters, L loonies.
R is how many dollars per loonie.



{{{system(q=2L, 0.25q+RL=12.50)}}}


{{{0.25(2L)+RL=12.50}}}
{{{0.5L+RL=12.5}}}
{{{L(R+1/2)=12&1/2}}}
{{{2LR+1=25}}}
{{{2LR=24}}}
{{{LR=12}}}
The question is really about quarters.
{{{2LR=24}}}
{{{qR=24}}}
{{{q=24/R}}}


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.
