A jar of coins contains nickels, dimes, and quarters. The total number of coins is 12 and the total value is $2.50. How many of each coin are there?

Answer 1

Answer #1

Let N means the number of nickels, D means the number of dimes and Q means the number of quarters.

then Total Coins : N + D + Q = 12

and total Value: .05N + .10D + .25Q = $2.50

then solve it, we get the values, D = 2, N = 1, Q = 9
