Assume the following scenario:

You are in charge of a retail category of merchandise at Penney's. You examined your sales results and was planning to invest money in the category for a new display and wondered how much business you would have to do to recover your investment of $$10,000.$ So you analyzed the numbers and came up with this:

Unit sales Margin on each item unit contribution of each item

$25035\%$ $ $4\mathrm{.}30$

$30045\%$ $ $5\mathrm{.}60$

$15025\%$ $ $2\mathrm{.}50$

D$.$ What is the weighted average contribution for the product line?

E$.$ What is the weighted average margin for the product line?

F$.$ How many units need to be sold to recover the investment?
