A road can be paved with either asphalt or concrete. Concrete costs $20,000/mile and lasts for 20 years. What is the maximum that should be spent on asphalt, which lasts only 10 years? The annual maintenance costs are $500/mile for both pavements. The cost of money = 8%.
An engineer will deposit 15% of her salary each year into a retirement fund. If her current annual salary is $80000 and she
expects that it will increase by 5% (g) each year, what will be the present worth of the fund after 35 years if it earns 5%
interest? (Answer: $400,000)

- A construction manager just starting in private practice needs a van to carry crew and equipment. She can lease a used van for $3910 per year, paid at the beginning of each year, in which case maintenance is provied. Alternatively, she can buy a used van for $5407 and pay for maintenance herself. She expects to keep the van for three years at which time she could sell it for $1045. What is the most she should pay for uniform annual maintenance to make it worthwhile to buy the van instead of leasing it, if her MARR is 20%? Enter your answer as follow: 123456arrow_forward7.

The generating set costs P 70,000 with a life of 10 years with a salvage value of P 10,000. The daily operating cost is P 50 per hour. During a brownout, the office operation will be delayed which cause a loss of P 150 per hour. At 18% interest rate, how frequent( in number of hours per year ) is the brownout to justify the purchase of the generator set?arrow_forward
