A commissionaire removed 76 coins, consisting of loonies and quarters, from a parking meter. If the value of the coins was $37.75, how many coins of each were removed? Start with let statements, assign variables and solve the system of equations.

Let x = the number of loonies

Let y = the number of quarters

Using these variables, we can create equations the represents the total cost and total number of coins.

x + y = 76                                   

eq1   -------> total number of coins

1.00x + 0.25y = 37.75                  

eq2  ------->  total cost

You now have a system of two equations.  Use either substitution/elimination methods to solve for x and y.

y=51 and x=25
