Target Cost: BIT
Target Cost = Target Price - Target Profit
If fixed overhead is allocated based on units of production, the fixed overhead cost per unit is
equal to $62.50 calculated as follows:

Given that it takes 2 hours ($20 total labor cost per unit/$10 per hr. wage rate) to produce
each unit of BIT and 5 hours ($50 total labor cost per unit/$10 per hr. wage rate) to
produce each unit of MORE, the total expected labor hours needed for the year are:

Total fixed overhead allocated per unit:
Since the cost per unit of BIT is below the target cost of $105.60, it is earning a return
greater than the desired rate. The cost per unit of MORE is above the target cost of $180, so
Reducing the number of setups required for one product while not reducing the related
overhead cost will change the allocation rate per setup and the total manufacturing cost per
unit for each product.

Total manufacturing cost per unit:
Since the cost per unit of BIT is still below the target cost of $105.60, it is earning a return
more than the desired rate. The cost per unit of MORE is still above the target cost of
$158.40, so it is earning lower than the desired return.
