Question

olanda 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

Answer 1

n + q = 28 (total coins)
0.05n + 0.25q = 4 (total value in dollars)

So the correct system is the first option.
