Charles buys factory-reconditioned hedge trimmers for $20 each and sells them online for $42 each. He has a fixed cost of $200 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)=42x and C(x)=20x+200. Find a formula for the function P(x)=R(x)−C(x). For what values of x is his profit positive?
