XYZ Construction Inc. wants to purchase a new pick-up truck. The price for the new truck is $46,679. The dealer allows XYZ to trade-in the old truck for $5,353. XYZ can payback the remaining balance through a 4-year payment plan. Given the agreed interest rate is 3% : How much is the monthly payment? If XYZ can only pay $761 monthly, and the dealer does not accept trade-in, given 3% interest rate, how much of the new pick-up truck can XYZ afford? On second thoughts, XYZ decides to keep the old truck. They can choose to retrofit it or not. The retrofit will cost $2,428. After the retrofit, the annual fuel and maintenance cost will be $719 for the first year and increases by $139 each year. XYZ 's minimum attractive rate of return is 4%. If XYZ will get rid of the old truck in six years, what is the total present cost of retrofit? Without the retrofit, the annual fuel and maintenance cost will be $1,830 for the first year and increases at a rate of 7% each year. If XYZ will get rid of the old truck in six years, what is the total present cost of not retrofit
