For a particular business, the cost of producing one item is $2 and the company has fixed costs of $150, so their
total costs for producing x items can be represented by c = 2x + 150. they sell each of these items for $5, so
their revenue for x items can be represented by r = 5x. find an expression that represents their profit for
selling x items. simplify your answer. (hint: remember that profit is revenue minus cost.)
