Assume that a company is selling a $ $950\mathrm{.}00$ mattress with a $ $50\mathrm{.}00$ promo code. What is the margin that company makes when it sells such a mattress $($consider COGS, delivery cost and cost of returned products$)?$ Use the following data to carry out your analysis

$-$Cost of Goods Sold $($COGS$)$ is $60\%.$ This is in line with other $$Big Mattress$$ firms $(62\%,$ Exhibit $2).$

$-$ On outbound delivery, assume the box costs $$5$ each, and on average, the UPS charge is $ $70\mathrm{.}00$ for a king mattress delivery.

$-$ Return rate on mattresses is $5\%.$ Cost to of disposal or arranging donation of mattress is $ $25\mathrm{.}00.$
