Question 887950

n and q for counts of nickels and quarters.


{{{n+q=53}}} and {{{0.05*n+0.25q=9.85}}}
The money equation
{{{5n+25q=985}}}
{{{highlight_green(n+5q=197)}}}
and
{{{highlight_green(n+q=53)}}}


Subtract the coin count equation from the simplified money count equation and quickly get
a value for q.
Use that to get n.


q=36
