A bag contains 23 coins consisting of quarters and nickels. The total value of the coins is $4.15. Which system of equations can be used to determine the number of quarters, q, and the number of nickels, n, in the bag?

0.05q + 0.25n = 4.15q + n = 23

5q + 25n = 23q + n = 4.15

25q + 5n = 23q + n = 4.15

0.25q + 0.05n = 4.15q + n = 23

Question 1/3
