    A movie theater charges 7.00 for adults and 2.00 for seniors citizens. On a day when 304 people paid for admission, the total receipt were 1118. How many who paid were adults ? How many were senior citizens?

    Let a be the number of adult tickets. Let s be the number of senior citizen tickets. We're given two equations:
    1. a + s = 304
    2. 7a + 2s = 1118
    We can solve this system of equations three ways:
    No matter which way we choose, we end up with the same answer:
    • a = 102
    • s = 202
