finding the cost when h=8

The correct answer is: $ 5300


    Given that;
    The cost to produce x surfboards in a factory is given by the function C(x) = 20x + 500
    The number of surfboards that can be produced in h hours is given by the function x(h) = 30h
    given that h=8
    Cost = 600h + 500 = 600 × 8 + 500 = 5300.
