Geneva Bottled Water Co$.$ is assembling a weighted average contribution margin chart to

better analyze differences between sales on $36oz.$ and the $20oz.$ bottled water. The sales

price per unit of the $36oz.$ bottled water is $$3\mathrm{.}69$ while the sales price per unit of the $20oz.$

bottled water is $$1\mathrm{.}08.$ The contribution margin per unit for the $36oz.$ bottle is $$2\mathrm{.}40$ and the

contribution margin of the $20oz.$ bottle is $$0\mathrm{.}12.$ The $20oz.$ bottle outsells the $36oz.$ bottle by

a $5$:$1$ relationship.

What is the weighted average contribution margin per unit on these two products?

A$.$ $$2\mathrm{.}42$

B$.$ $$2\mathrm{.}02$

C$.$ $$0\mathrm{.}50$

D$.$ $$3\mathrm{.}00$
