Exercise Planet, Inc, produces two basic types of weight-lifting equipment, Model 9 and Model 14. Pertinent data are as follows: E7 (Click the icon to view the data.) The weight-lifting craze suggests that Exercise Planet can sell enough of either Model 9 or Model 14 to keep the plant operating at full capacity. Both products are processed through the same production departments. Read the requirements. Before determining which products to produce, let's calculate the contribution margin per unit and the contribution margin per machine hour for each machine. (Reduce the foxed manufacturing overhead to the lowest possible ratio of machine hours in order to calculate the contribution margin per machine hour Example: 8:4 would be 2:1. Enter the amounts to the nearest cent.) Exercise Planet, inc. should produce: A. Model 14, since this model results in the higher operating income per unit. B. Model 14, since this model resuits in the higher contribution margin per unit. c. Model 9. since this model results in the higher contribution margin per machine hour. D. Both Model 9 and Model 14 since both models provide positive contribution margins. Exercise Planet, Inc, produces two basic types of weight-lifting equipment, Model 9 and Model 14.
