39 of 40 The revenue, in thousands of dollars, that a company earns selling lawnmowers can be modeled by R(x) = 90x-x and the company's total profi in thousands of dollars, after selling x lawnmowers can be modeled by P(x) = x+30x-200. Which function represents the company's cost, in thousands of dollars, for producing lawnmowers? (Recall that profit equals revenue minus cost.) OA. C(x)=60x + 200 OB. C(x)=-60x - 200 C. C(x)= -2x - 60x-200 D. C(x)=2x +60x+200
