Charles buys factory-reconditioned hedge trimmers for $20 each and sells them online for $42 each. He has a fixed cost of $300 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 + 300. 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)=.
