A Methods and Measurements Analyst needs to develop a time standard for a certain task. The task involves use of a ruler, square
, and portable electric saw to mark and cut the "notch" in a rafter (a standard carpentry task of home construction). In a preliminary study, he observed one of his workers performing this task five times. The observations were made in an airconditioned, well-lit training facility, at ground level, with all tools and equipment clean and readily available. Observation: 1 2 3 4 5 Task time (seconds): 82 74 80 83 76 a. What is the actual average time for this task? b. What is the normal time for this task if the employee worked at a 20% faster pace than is typical for adequately trained workers? c. What is standard time for this task if allowances sum to 14%? d. If the analyst then thought more carefully about his experiment and decided that the allowances needed to be increased to match the real (outside, not air-conditioned) work environment, and that the proper allowance was not 14% but 20%, what is the revised standard time?

Answer:
$0.72
Explanation:
total direct materials = $125,000
total variable selling costs = $15,000
total variable costs = $140,000
variable cost per unit = $140,000 / 1,000 units = $140 per unit
contribution margin ratio = (sales price - variable cost) / sales price = ($500 - $140) / $500 = 72%
this means that per dollar of sales, $0.72 are left to cover fixed costs and contribute to operating income
