An automated car wash serves customers with the following serial process: pre-treat, wash, rinse, wax, hand dry. Each of these steps is performed by a dedicated machine except for the hand dry step, which is performed manually on each car by one of three workers. The steps of the process have the following processing times: Pre-treat: 1 minute per car
Wash: 5 minutes per car
Rinse: 2 minutes per car
Wax: 3 minutes per car
Hand dry: 8 minutes per car
Round "Flow rate" and "Utilization of hand dry" and "Cycle time" to 2 decimal places.
a. Which resource is the bottleneck of this process? Wash
b. If the car wash has a demand of 19 cars per hour, what is the flow rate of the process? 10.00 customers per hour
c. If the car wash has a demand of 19 cars per hour, what is the utilization of the machine that performs the Wax process? 67 percent
d. If the car wash has a demand of 15 cars per hour, what is the utilization of hand dry? percent
e. If the car wash has a demand of 15 cars per hour, what is the cycle time of the process (minutes)? minutes
f. Starting from an empty system (and assuming the stations can work independently), how long would it take (minutes) to wash 8 cars? 72 minutes

The chromosome manufacturing company produces two products, x and y. the company president, jean mutation, is concerned about the fierce competition in the market for product x. she notes that competitors are selling x for a price well below chromosome's price of $13.50. at the same time, she notes that competitors are pricing product y almost twice as high as chromosome's price of $12.50.ms. mutation has obtained the following data for a recent time period: product x product y number of units 11,000 3,000 direct materials cost per unit $3.23 $3.09 direct labor cost per unit $2.22 $2.10 direct labor hours 10,000 3,500 machine hours 2,100 1,800 inspection hours 80 100 purchase orders 10 30ms. mutation has learned that overhead costs are assigned to products on the basis of direct labor hours. the overhead costs for this time period consisted of the following items: overhead cost item amount inspection costs $16,200 purchasing costs 8,000 machine costs 49,000 total $73,200using direct labor hours to allocate overhead costs determine the gross margin per unit for product x. choose the best answer from the list below.a. $1.93b. $3.12c. $7.38d. $2.43e. $1.73using activity-based costing for overhead allocation, determine the gross margin per unit for product y. choose best answer from list below.a. $10.07b.
