    Answer: They sold 173 adult tickets and 43 student tickets.

    Step-by-step explanation:

    Equations:

    • 10.25x + 8y = 2117.25
    • x + y = 216
    • X = adult tickets.
    • Y = student tickets.

    Solving:

    • 10.25x + 8(216 – x) = 2117.25 (y = 216 – x, substitute in for y)
    • 10.25x + 1728 – 8x = 2117.25 (distribute)
    • 2.25x = 389.25 (combine like terms)
    • x = 173
    • 173 + y = 216 (solve for y)
    • y = 43
