Kevin and Randy have a jar containing 48 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $9.20. How many of each coin do they have?

Let 'q' and 'n' stand for the number of quarters and nickels respectively. From the question, we can write:
q+n=48 (total number of coins)
.25q+.05n=9.20 (total value in jar)
Using Algebrator to solve for 'n' and 'q', we get:
n=14
q=34
