how do i set up the chart for MSRP

Acme Corporation is a manufacturer of a new line of energy-efficient, small refrigerators that are used in assisted living centers, college dorms, company smaller common-area kitchens, hotels, individual offices, and RVs. The new line of refrigerators include a small size (24w 240 24h) and medium size (24w *24d"36h). The refrigerator's color options are black, brown, and white. There is an option to have customized panels that attach to the refrigerator to make it more decorative. The customization panels are similar to wallpaper and have five selections. Competitors are brand names such as Whirlpool and Black and Decker to less well-known names firms, such as Avanti and Midea. Also, they are mindful of ensuring that MSRP is maintained by a channel discount (margin) structure and channel conflict is minimized. Suggested MSRP for the small size is $109 and the medium size is $159. Given the required margins by each of the channels, calculate the margins dollars and margin percentage that would result. In the appliances market the following margins are required: Wholesalers/Distributors/NGO @20%: Retailers/Rural Retailers/Rural ENTR @30%. Acme's cost to manufacture the small refrig is $48 and the medium size is $69. Acme expects to earn 20% margin Note: You may find, as we did with Pixel, that the MSRP might differ slightly from the suggested MSRP. Be sure to discuss what this means for the channels that carry the product
