  1. Answer:

    • $2.65

    Step-by-step explanation:

    Let chocolate bar cost be c and blow pop cost be b

    Then we have equations:

    • 5c + 8b = 23.25
    • 2c + 13b = 21.55

    Multiply the first equation by 13 and the second one by 8 and subtract:

    • 13(5c + 8b) – 8(2c + 13b) = 13(23.25) – 8(21.55)
    • 65c – 16c = 129.85
    • 49c = 129.85
    • c = 129.85/49
    • c = 2.65

    Chocolate bar costs $2.65
