    Answer: the price of an adult ticket is $21.5 while the price of a child ticket is $15.5

    Step-by-step explanation:

    Let x represent the price of an adult ticket.

    Let y represent the price of a child ticket.

    At an amusement park, the cost of 3 adult tickets and 4 children’s tickets is 126.50. This means that

    3x + 4y = 126.5 – – – – – – – – – – – 1

    Another customer paid 120.50 for 2 adult tickets and 5 children’s tickets. This means that

    2x + 5y = 120.5 – – – – – – – – – – 2

    Multiplying equation 1 by 2 and equation 2 by 3, it becomes

    6x + 8y = 253

    6x + 15y = 361.5

    Subtracting, it becomes

    – 7y = – 108.5

    y = – 108.5/ -7

    y = 15.5

    Substituting y = 15.5 into equation 1, it becomes

    3x + 4 × 15.5 = 126.5

    3x + 62 = 126.5

    3x = 126.5 – 62 = 64.5

    x = 64.5/3 = 21.5
