x items is R=68x−0.3x^2. How many items must be sold to obtain a weekly profit of $200?

  1. Profit = Revenue - Cost
    So, you want to find x such that

    (68x-0.3x^2)-(50x+40) = 200
    or, in a more standard form,
    0.3x^2-18x+240 = 0
    or
    x^2-60x+800 = 0
    (x-40)(x-20) = 0
    ...

  2. The revenue for a company selling x products is modeled by the polynomial expression 5x - 0.4x2 dollars. The operating cost for the company is modeled by the polynomial expression 0.6x + 500 dollars.

    Show your understanding by writing an expression models the profit in dollars of the company as a function of the number of products sold?
