    Let us assume rent for a child = $x per hour and

    Rent for an adult = $ y per hour.

    We are given number of children = 3.

    Number of adults = 1.

    Rent for 3 children at the rate $x per hour = 3*x = 3x.

    Rent for 1 adult at the rate $y per hour = 1*y = y.

    We are given number of hours of rafting trip = h hours.

    Total cost of 3 children and 1 adult for h hours = h times (Cost of 3 children and 1 adult for each hour).

    = h * (3x+y).

    Therefore, h (3x+y) is the final expression for the total cost of h hours of rafting trip.

    If you are given values of x, y or h, you can plug those values in this expression.
