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
