Chapter 5, Problem 55P
The upturned wingtips on jet aircraft reduce drag and increase lift. Wingtips save on fuel consumption, averaging 4% of the total fuel bill. A single set of wingtips can annually save 45,000gallonsof jet fuel costing $3 per gallon. (Fuel is the biggest operating expense of an airline company.) Furthermore, 100 metric tons of carbon dioxide emissions each year will be avoided, and maintenance expenses will be reduced. Wingtips cost $1 million to install. The airline company’s MARR is 20%. Considering only the fuel savings, what is the simple payback period for the wingtips? What is the discounted payback period? (5.8)

Cindy and Steven are recently married and are both chefs. They have recently graduated from culinary school and are making a starting salary of $15.00 as a sous-chef. They both work 10 hour days, six days a week. Because they are chefs at a mid- level restaurant they live in the downtown core where it is located. The rent on their one bedroom apartment is $1125/month. This includes all utilities. However, they pay an additional $75 for cable and internet. Their joint cell phone bill is $60.00 and they opt not to have a landline to save money. Because they live downtown they have also chosen not to buy a car and spend about $200 a month on public transportation. They eat most meals for free at the restaurant where they work so their grocer bill is only about $200 a month. Do Cindy and Steven earn enough money to cover their expenses

- Suppose I have computed the cost of carbon per mile for my car at 0.011 per mile. Assume that the interest rate is 5% and that I drive the car 30,000 miles per year. What is present value of the carbon expense for five years? You will need to use the PV function in Excel or a financial calculator. In Excel the present value of a stream of monetary cash flows is given by -PV(rate, number of payments, payment amount) where rate is the interest rate. We enter the payment in Excel as a positive number. You can also compute the carbon cost per year and then discount those five values back to the present.arrow_forwardABC university tuition fees can be paid by on-time payment (pay total amount due when classes start at the cost of 90,000 pesos per year) or early-bird payment (pay total amount due 1 year in advance with a 10% discount).
