Textbook Question

Chapter 4, Problem 81P

You want to take out a $450,000 loan on a 20-year mortgage with end-of-month payments. The annual rate of interest is 3%. Twenty years from now, you will need to make a $50,000 ending balloon payment. Because you expect your income to increase, you want to structure the loan so at the beginning of each year, your monthly payments increase by 2%.

a. Determine the amount of each year’s monthly payment. You should use a lookup table to look up each year’s monthly payment and to look up the year based on the month (e.g., month 13 is year 2, etc.).
b. Suppose payment each month is to be the same, and there is no balloon payment. Show that the monthly payment you can calculate from your spreadsheet matches the value given by the Excel PMT function PMT(0.03/12,240, −450000,0,0).

The average completion time (flow time) for the sequence developed using the FCFS rule = 11.75 days (round your response to two decimal places). The percentage utilization for the sequence developed using the FCFS rule = 42.55 % (enter your response as a percentage rounded to two decimal places). b) Using the SPT (shortest processing time) decision rule for sequencing the jobs, the order is (to resolve a tie, use the order in which the jobs were received): An Alabama lumberyard has four jobs on order, as shown in the following table. Today is day 205 on the yard's schedule. In what sequence would the jobs be ranked according to the decision rules on the left: Job Due Date A 212 B 209 C 208 D 210 Duration (days) 6 3 3 8 Sequence 1 Job B 2 3 4 A D The average tardiness (job lateness) for the sequence developed using the SPT rule = 5.00 days (round your response to two decimal places). The average completion time (flow time) for the sequence developed using the SPT rule = 10.25 days…
