x=nickels
44-x=quarters
.05x+.25(44-x)=5.00
.05x+11.00-.25x=5.00
-.20x=-6.00
x=30 nickels ($1.50)
44-x=14 quarters ($3.50)
They add to $5.00

VARIABLES
n nickels
q quarters

EQUATIONS
system%28n%2Bq=44%2C0.05n%2B0.25q=5%29

SOLVE
-
Multiply the money count equation by 20 to get simple whole number coefficients and constant.
-
n%2B5q=100
-
The system to solve should now be system%28n%2Bq=44%2Cn%2B5q=100%29 and n is easily eliminated to quickly find q.
-
4q=56
highlight%28q=14%29-------number of quarters....
