D Question 22 1 pts a Queen's Wedding Dress makes custom wedding dresses. During a particular week, each of the eight employees worked 42 hours to produce a batch of 96 dresses. The dresses are sold to retail distribution at $215 each. What is the labor productivity of this manufacturing process in terms of dollars per labor hour? (Enter your response rounded to two decimal places.) Exercise Problem 5-7 Fullerton Fitness Inc. produces low cost, highly durable home gym equipment for beginners. Typically, out of the 100 units that begin production each month, only 90 percent are considered good enough to sell. The other 10 percent are scrapped due to quality problems that are identified after they have completed the production process. Each home gym unit sells for $1,000. Because some of the production process is automated, each unit only requires 10 labor hours. Each employee works an average of 160 hours per month. Labor is paid at $10 per hour, materials cost is $320 per unit, and overhead is $12,000 (estimated at 1.2 times the labor cost). The multifactor productivity ratio is? (Enter your response rounded to two decimal places.) 90x$1000 1.67 100x10x$10 + 100x$320 + $12,000 Exercise Problem 5-7 (continued) Evaluate the following three scenarios independently based on the current multifactor productivity. (Enter your response rounded to two decimal places.) What is the new multifactor productivity ratio if the sales price is increased by 20%? 90x$1200 100X10x $10 + 100X$320 + $12,000 2.00 What is the new multifactor productivity ratio if the quality is improved so that only 5% are defective? 95x$1000 = 1.76 100x10x $10 + 100x$320 + $12,000 Exercise Problem 8-9 Student tuition at Great University is $150 per semester credit hour. The state supplements school revenue by $50 per semester credit hour. Average class size for a typical 3-credit course is 45 students. Labor costs are $4,000 per class, materials costs are $20 per student per class, and overhead costs are $22,000 per class. The multifactor productivity ratio currently is 1.00 and the labor productivity ratio is $120.54 per hour if the instructors work on an average of 14 hours per week for weeks for each 3-credit class of 45 students. Exercise Problem 8-9 (continued) To improve its finance, the university decided to change its tuition and class size. The new overhead costs will be $31,000 per class section. Labor costs will increase to $6,000 per 3-credit course. Material costs will be about $25 per student for each 3-credit course with an average class size of 70 students. Tuition will be $190 per semester credit, which is supplemented by state support of $50 per semester credit. What would be the new multifactor productivity ratio for a 3-credit course? (Enter your response rounded to two decimal places.) ($190 + $50)x3x70 $6,000 + 70x$25 + $31,000 = 1.30
