A plant manager wants to know the present worth of the maintenance costs for a reconditioned assembly line. An industrial engineer, who designed the system, estimates that the maintenance costs are expected to be zero for the first three years, $2000 in year four, $2500 in year five, and amounts increasing by $500 each year through year 10. At an interest rate of 8% per year compounded semiannually, the value of n to use in the P/G equation is: O 14 O 10 07

Improvised explosive devices (IEDs) are responsible for many deaths in times of strife and war. Unmanned ground vehicles (robots) can be used to disarm the IEDs and perform other tasks as well. If the robots cost $165,000 each and the military arms unit signs a contract to purchase 3,500 of them now and another 9,000 one year from now, what is the equivalent annual cost of the contract over a 10- year period at 9% per year interest? The equivalent cost of the contract is determined to be $2254312500

An engineering technology group just purchased new CAD software for P85,000 now and annual payments of P15,000 per year for six years starting 3 years from now for annual upgrades. What is the equivalent annual cost of the all the payments made if the interest rate is 8% per year?

How much must you deposit each year into your retirement account starting now and continuing through year 15 if you want to be abl to withdraw $100,000 per year forever, beginning 34 years from now? Assume the account earns interest at 15% per year. The amount to be deposited is determined to be $

Costs associated with the manufacture of miniature high-sensitivity piezoresistive pressure transducers is $80,000 per year. A clever industrial engineer found that by spending $18,000 now to reconfigure the production line and reprogram two of the robotic arms, the cost will go down to $54,000 next year and $49,000 in years 2 through 5. Using an interest rate of 15% per year, determine the present worth of the savings due to the reconfiguration. The present worth of the savings is determined to be $
