A doctor is on contract to a medium-sized oil company to provide medical services at remotely located, widely separated refineries.
The doctor is considering the purchase of a private plane to reduce the total travel time between refineries. The doctor can buy a used
Learjet 31A now for $1.700 million or wait for a new very light jet (VLJ) that will be available 3 years from now. The cost of the VLJ will
be $2.600 million, payable when the plane is delivered in 3 years. The doctor has asked you, his friend, to determine the present
worth of the VLJ so that he can decide to buy the used Learjet now or wait for the VLJ. The MARR is 14.00% per year, and the inflation
rate is projected to be 3.200% per year.
a) What is the present worth of the VLJ with inflation considered?
b) Which plane should he buy?
The present worth of the VLJ with inflation considered is
He should buy the used Learjet now ✓
A small company heats its building and spends $8,800 per year on natural gas for this purpose. Cost increases of natural gas are expected to be 9% per year starting
one year from now (i.e., the first cash flow is $9,592 at EOY one). Their maintenance on the gas furnace is $355 per year, and this expense is expected to increase by
12% per year starting one year from now (i.e. the first cash flow for this expense is $397.60 at the EOY one). If the planning horizon is 14 years, what is the total
annual equivalent expense for operating and maintaining the furnace? The interest rate is 15% per year.

The doctor is considering the purchase of a private plane to reduce the total travel time between refineries. The doctor can buy a used Learjet 31A now for $1.1 million or wait for a new very light jet (VLJ) that will be available 3 years from now. The cost of the VLJ will be $2.1 million, payable when the plane is delivered in 3 years. The doctor has asked you, his friend, to determine the present worth of the VLJ so that he can decide to buy the used Learjet now or wait for the VLJ.
