You can put this solution on YOUR website!
Count of nickles, n
Count of quarters, q

n%2Bq=13, and 0.05n%2B0.25q=2.45.
The sum of the quantity of coins is 13, as given and symbolized.
Think about the units involved in the numbers for the money value equation.
0.05%2A%28dollars%2Fnickle%29 and n%2Anickles would give the term, ...

The system of equations is
---------------------------
n%2Bq=13
---------------------------
0.05n%2B0.25q=2.45
