Trayvon sells candy bars at a price of $3 each. He purchases every order of 200 candy bars for $350. If the cost of shipping is $0.15 per bar, what is Trayvon’s profit function?
A profit function is the revenue function minus the cost function. Since the revenue will at R(x) = 3x and the cost will be at C(x) = -350 - 0.15x. The profit function will be equal to P(x) = 2.85x - 350 for the first 200 candy bars.
