a. (2 points) How many small and large offices should thedeveloper build?

b. (4 points) What is the total optimal monthly revenue?

c. (2 points) If the developer implements the optimal solution,what amount of square footage would remain unused?

d. (5 points) What is the impact on the optimal allocation ofoffices and the objective function value if small offices can berented for $800 per month rather than $600 per month?

e. (2 points) What impact would an increase in 52,800 sq. ft ofadditional footage have on the optimal objective functionvalue?

f. (5 points) What impact will an increase in the monthly rentalof small offices to $650 and simultaneous decrease to $800 in themonthly rental of large offices have on the current optimalsolution and the objective function value?

A real estate developer is planning to build an office complex. There are three office sizes currently under consideration: small, medium, and large. Small offices can be rented for $600 per month, medium offices can be rented for $750 per month, and large offices can be rented for $1,000 per month. Each small office requires 600 square feet, each medium office requires 800 square feet, and each large office requires 1,000 square feet. The current plot of land available to the developer is 100,000 square feet. The developer wants to ensure that the office complex has at least 3 units of each office size. Moreover, zoning restrictions limit the total number of offices to 50. The developer solved this problem such that he could accrue maximum rent from the small, medium, and large offices he builds. Your job is to analyze this sensitivity report and answer the following questions: Sensitivity Report Adjustable Cells Cell $B$4 $C$4 $D$4 Name Optimal Values Small Optimal Values Medium Optimal Values Large Final Reduced Value Cost 3 0 3 0 44 0 Objective Coefficient 600 750 1000 Allowable Allowable Increase Decrease 400 1 E+30 250 1E+30 1 E+30 250 Constraints Cell Final Shadow Value Price Constraint Allowable Allowable R.H.

(Solved) : Caterpillar Salesperson Comes Office Describes New Front End Loader Say Save Money Accord Q40719084 . . .

A. Caterpillar salesperson comes to your office and describes anew front-end loader that they say will save you money. Accordingto the literature it will cost $152,000 and has an effectiveservice life of 12 years at which time it has a typical salvage(resale) value of $65,000. Your research indicates that thisliterature is indeed accurate. You review your productivity dataand estimate that this equipment will save you 2,000 per month. Themachine will, however, require a fixed monthly maintenance cost of$600. Your alternative investment would earn 4 percent for 5 yearsand 6 percent for the following 7 years (compounded yearly). Wouldthe equipment be a good purchase or should you invest in thealternative account?
