    Karmen just got hired to work at Walmart. She spent $15 on her new uniform and she gets paid $8 per hour. Write an equation that represents how much money she profits after working for a certain number of hours. How many hours will she have to work for in order to buy a new snowboard ( which costs $450)

    Her profit equation P(h) where h is the number of hours worked is:
    P(h) = 8h - 15
    Note: We subtract 15 as the cost of Karmen's uniform.

    Next, we want to see how many hours Karmen must work to buy a new snowboard which costs $450.
    We set the profit equation equal to $450
    8h - 15 = 450

    Typing 8h - 15 = 450 into the search engine, we get h = 58.13. We round this up to 59 hours.
