Top of Form Flag this Question Question 1 10 pts In a job shop, effective capacity is only 50 percent of design capacity, and actual output is 80 percent of effective output. What design capacity would be needed to achieve an actual output of eight jobs per week? Flag this Question Question 2 10 pts A real estate agent is considering changing her cell phone plan. There are three plans to choose from, all of which involve a monthly service charge of $20. Plan A has a cost of $.45 a minute for daytime calls and $.20 a minute for evening calls. Plan B has a charge of $.55 a minute for daytime calls and $.15 a minute for evening calls. Plan C has a flat rate of $80 with 200 minutes of calls allowed per month and a charge of $.40 per minute beyond that, day or evening. 1. Determine the total charge under each plan for this case: 120 minutes of day calls and 40 minutes of evening calls in a month. total charge for plan A total charge for plan B total charge for plan C 2. Prepare a graph that shows total monthly cost for each plan versus daytime call minutes. Include the graph in your Excel file. 3. If the agent will use the service for daytime calls, over what range of call minutes will each plan be optimal? # mins for A to be optimal # mins for B to be optimal # mins for C to be optimal 3. Suppose that the agent expects both daytime and evening calls. At what point (i.e., percentage of call minutes for daytime calls) would she be indifferent between plans A and B? proportion of daytime mins proportion of nighttime mins Flag this Question Question 3 10 pts A manager must decide how many machines of a certain type to purchase. Each machine can process 100 customers per day. One machine will result in a fixed cost of $2,000 per day, while two machines will result in a fixed cost of $3,800 per day. Variable costs will be $20 per customer, and revenue will be $45 per customer. 1. Determine the break-even point for each range. break-even point for 1 machine break-even point for 2 machines 2. If estimated demand is 90 to 120 customers per day, how many machines should be purchased? Flag this Question Question 4 10 pts An assembly line with 17 tasks is to be balanced. The longest task is 2.4 minutes, and the total time for all tasks is 18 minutes. The line will operate for 450 minutes per day. 1.
