Using the same price-demand function as in question #2, that is, p(x) = 1200 - 3x, what is the revenue function for the camera?

R(x) = 1200x - 3x^{2}

R(x) = 1200 - 3x^{2}

R(x) = 1200 - 3x

If it has been determined that the revenue function for a certain item is R(x) = -0.3x^{2}+ 90x and the cost function for the item is C(x) = 32x + 850, write the profit function for the item.

P(x) = -0.3x^{2}+ 58x - 850

P(x) = -0.3x^{2}+ 58x + 850

P(x) = -0.3x^{2}+ 122x - 850
