    Answer:

    The domains are;

    0 < x < 3 for f(x) = 15

    3 ≤ x ≤ 7 for f(x) = 22

    7 < x ≤ 15 for f(x) = 30

    Step-by-step explanation:

    The duration the amusement park is opened, t = 15 hours

    The number of days the amusement is opened = 7 days a week

    The prices for the admission are;

    x < 3 hours = $15

    3 ≤ x ≤ 7 hours = $22

    x > 7 hours = $30

    The functions are;

    f(x) = 15 when x < 3; The domain = 0 < x < 3

    f(x) = 22 when 3 ≤ x ≤ 7; The domain = 3 ≤ x ≤ 7

    f(x) = 30 when x > 7; The domain = 7 < x ≤ 15.
