Aprofit formula for dining plates can be modeled by the function p(d) = –15d2 + 1,200d – 2,000. the manufacturer is thinking of increasing the selling price by 50%, which can be modeled by the function l(d) = 1.5d. which composite function can be used to find the new profit formula after the price increase? p(d) = –7.5d2 + 600d – 2,000 p(d) = –3.75d2 + 600d – 2,000 p(d) = –22.5d2 + 1,800d – 2,000 p(d) = –33.75d2 + 1,800d – 2,000
