    Manufacturing Cost

    The weekly production cost C of manufacturing x watches is given by the formula C = 4000 + 2x, where C is in dollars.

    A. What is the cost of producing 3000 watches?
    B. What is the cost producing 4000 watches?
    C. Replace C with y to become a linear equation and graph
    the equation.

    Questions:

    1. For A and B above, must I replace x with 3000 and then 4000, respectively, to find the cost C?
    2. For C, the given formula become y = 4000 + 2x. Yes?
    I must then graph y = 4000 + 2x on the xy-plane? True?

    Re: Manufacturing Cost

    Let x = 3000

    C = 4000 + 2(3000)

    C = 4000 + 6000

    Cost = 10,000 dollars.

    Let x = 4000

    C = 4000 + 2(4000)

    C = 4000 + 8000

    C = 12,000 dollars
