Charles buys factory-reconditioned hedge trimmers for $20 each and sells them online for $43 each. He has a fixed cost of $600 per month. If x is the number of hedge trimmers he sells per month, then his revenue and cost (in dollars) are given by R(x) = 43x and C(x) = 20x + 600. Find a formula for the function P(x) = R(x) – C(x). For what values of x is his profit positive? ... The formula is P(x) =||
