A profit formula for dining plates from the previous year was modeled by the function P(d) = –15d2 + 1,200d – 2,000. The manufac
turer noticed an increase in the number of units sold by 50% the next year, 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 increase in the number of units?
