Kevin and randy mouse have a jar containing 97 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $14.25. How many of each type of coin do they have?

Let the number of nickels =N

The number of quarters    = 97 - N

 

0.05N  +  0.25[97 -N] = 14.25, solve for N

N = 50 Nickels

97 - 50 = 47 Quarters
