Yolanda paid for her movie ticket using 28 coins, all nickels and quarters. The ticket cost $4. Which system of linear equations can be used to find the number of nickels, n, and the number of quarters, q, Yolanda used?


n + q = 28
0.05n + 0.25q = 4

n + q = 4
5n + 25q = 28

n + q = 28
5n + 25q = 4

n + q = 4
0.05n + 0.25q = 28

n + q = 28
0.05n + 0.25q = 4

Explanation: n+q=28 because there are 28 coins total. 0.05n+0.25q=4 because nickels are $0.05 and quarters $0.25, and their total value is $4.
