Finally, you must pass the road exam. At each of these steps, 10 percent, 15 percent, and 40 percent of driver’s license hopefuls fail to fulfill the step’s requirements.You are only allowed to take the written exam if your identification is approved, andyou are only allowed to take the road test if you have passed the written exam.Each step takes 5, 3, and 20 minutes, respectively (staff members administering writtenexams need only set up the applicant at a computer). Currently, the DMV staffs 4 peopleto process license applications, 2 to administer written exams, and 15 to judge the roadexam. DMV staff work 8 hours per day.a.

Before completing production, a product must passthrough three stages of production. On the average, a newproduct begins at stage 1 every 6 minutes. The average timeit takes to process the product at each stage is as follows:stage 1, 3 minutes; stage 2, 2 minutes; stage 3, 1 minute.After finishing at stage 3, the product is inspected (assumethis takes no time). Ten percent of the final products arefound to have a defective part and must return to stage 1 andgo through the entire system again. After completing stage3, 20% of the final products are found to be defective. Theymust return to stage 2 and pass through 2 and 3 again. Onthe average, how many jobs are in the system?
