    A dog walker charges a flat rate of $6 per walk plus an hourly rate of $30. How much does the dog walker charge for a 3 hour walk?

    Set up the cost equation C(h) where h is the number of hours:
    C(h) = Hourly rate * h + flat rate
    C(h) = 30h + 6

    The question asks for C(h) when h = 3:
    C(3) = 30(3) + 6
    C(3) = 90 + 6
    C(3) = 96
