A Construction Company has just purchased a fleet of five truck to be used for delivery
in a particular city. Initial cost was $3000 per truck and the expected life and salvage
value is 12 years and $700 respectively. The combine insurance, maintenance, gas and
lubrication cost are expected to be $1000 for the first year and to increase by $100 per
year thereafter, while delivery service will bring an extra $3000 (revenue) in every 2
years for the company. If the interest is 12% per year find the total cost of this investment.
