Anne Sugar makes large ceramic pots for use in outdoor landscaping. She currently has two models, one square and the other round. Because of the size of Anne$$s creations, only one pot can be fired in the kiln at a time. Information about each model follows:

$$SquareRoundSales price$ $94$$ $139$Variable cost$ $54$$ $90$Firing time$2\mathrm{.}5$hours$3\mathrm{.}5$hours

Assume Anne can sell as many pots as she can create but is limited as to the number of hours that the kiln can be run.

Required:

Compute the contribution margin per unit and contribution margin per hour of firing time.

Which type of pot should Anne produce to maximize her short$-$term profit?
