Let represent the number of quarters. Then is the value of those quarters in cents. Since there are 33 less nickels than quarters, must represent the number of nickels. then represents the value of the nickels in cents. The value of the quarters plus the value of the nickels is $20.25, but that is the same as 2025 cents. Therefore:



Solve for to get the number of quarters. Subtract 33 to find the number of nickels.

Oh, by the way:



would work just as well. It is just that I would rather work with integer coefficients given the choice.
