=+Budgeted units produced 9,000 9,000 9,000 Total process hours per unit 3 3 2 Reactor hours per unit 1.0 0.8 0.5 Unit selling price $165 $128 $115 Direct materials cost per unit $110 $75 $85 The reaction operation is part of the total process for each of these three products.

Thus, for example, 1.0 of the 3 hours required to process ethylene are associated with the reactor.

Instructions 1. Determine the unit contribution margin for each product.
