Final answer:
To calculate the desired profit per unit, subtract the operating expenses and the cost from the selling price per unit.
Step-by-step explanation:
a. To calculate the desired profit per unit, we need to subtract the operating expenses and the cost from the selling price per unit. The operating expenses are 26% of the cost, and the profits are 70% of the cost. Therefore, the desired profit per unit can be calculated as follows:
Desired Profit per unit = Selling price per unit - Operating expenses - Cost
Since we have only been given the cost per unit, we cannot calculate the desired profit per unit.
