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:

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
