(10 points) Harvard Office Products (HOP) produces three different paper products at its Quincy plant: Supreme, Deluxe, and Regular. Each product has its own dedicated production line at the plant. It currently uses the three-part classification for its manufacturing costs: direct materials, direct manufacturing labor, and manufacturing overheads costs. Total manufacturing overheads of the plant in June 2019 are $200 million ($20 million of which are fixed).
