Final answer:
The amount saved with the Milewise program depends on its specific cost structure, which is not provided. Efficient driving options and leasing concerns are also discussed, alongside an example to calculate daily average use.
Step-by-step explanation:
The question is requesting information on potential savings with the Milewise program for someone who drives less than 5,000 miles per year. Although specifics about Milewise aren't provided, it's implied that this program may offer cost savings for low-mileage drivers. To determine how much one can save by using Milewise, additional information on the program's cost structure is necessary, which the question doesn't supply.
An efficient driving option is to use less fuel per person than a fully-occupied airplane, which gets 90 m.p.g. per passenger. It may be challenging to find cars that perform this efficiently, but it is not impossible, especially with the advent of hybrid and electric vehicles.
Leasing is another alternative for getting a newer vehicle at a smaller monthly payment. However, it is important to take into account that if you drive the vehicle more than 10,000 miles per year, you might incur extra charges for the additional mileage.
Using an example from a textbook, we can get an idea of personal usage. If a household has two vehicles, with one driving 400 miles using 22 gallons of gasoline and the other 8,660 miles using 69 gallons, we can calculate the daily average use per person and compare this to national averages to see how usage stacks up.
