Variable costs include the labor costs of the medical technicians at the lab. Fixed costs of $500,000 per year include building and equipment costs and the costs of administration. A basic "unit" is a routine drug test administered. A retest is given if there is concern about the results of the first test, particularly if the test indicates that the athlete has taken drugs that are on the banned drug list. Retests are not done by the laboratory that performed the basic test. A "vital" test is the laboratory's code for a high-profile case. This might be a test of a famous athlete and/or a test that might be challenged in court. The laboratory does extra work and uses expensive expert technicians to ensure the accuracy of vital drug tests. Limitless Labs is subject to a 20 percent tax rate.

Explanation / Answer

contribution margin per unit

Basic = 720-230 = 490

Retest = 1075-600 = 475

Vital = 4660-3130 = 1530


sales mix

Basic = 700/1000 = 70%

Retest = 20%

Vital = 10%


wt avg Cm per unit = 0.7*490+0.2*475+0.1*1530 = $591
