n and q for NICKELS and QUARTERS

system%280.05n%2B0.25q=11.9%2Cn%2Bq=62%29
Very simple typical linear system application exercise
-
Simplify the money count equation first.
100%280.05n%2B0.25q%29=100%2A11.90
5n%2B25q=1190
%281%2F5%29%285n%2B25q%29=%281%2F5%291190
n%2B5q=238


The system to solve should take the form, system%28n%2B5q=238%2Cn%2Bq=62%29.
