Using the same price-demand function as in question #2, that is, p(x) = 1850 - 5x, what is the revenue function for the camera?

R(x) = 1850x - 5x^{2}

R(x) = 1850 - 5x^{2}

R(x) = 1850 - 5x

If it has been determined that the revenue function for a certain item is R(x) = -0.4x^{2} + 120x and the cost function for the item is C(x) = 43x + 1500, write the profit function for the item.

P(x) = -0.4x^{2} + 77x - 1500

P(x) = -0.4x^{2} + 77x + 1500

P(x) = -0.4x^{2}+ 163x - 1500
