High-profile vehicles have poor fuel efficiency because of increased wind resistance from their large front area. one company claims that by spending $560 on its friction-reducing deice, the fuel efficiency of a pickup truck will increase by 25%. assuming the devise works as claimed, for a vehicle that currently gets 20 miles per gallon, how many miles would the owner have to drive each year to break even in 5 years ? assume the cost of gasoline is $3.50 per gallon and the interest rate is 10% per year.

Draw a flowchart for a process of interest to you, such as a quick oil-change service, a factory process you might have worked in, ordering a pizza, renting a car or truck, buying products on the internet, or applying for an automobile loan. identify the points where something (people, information) waits for service or is held in work-in-process inventory, the estimated time to accomplish each activity in the process, and the total flow time. evaluate how well the process worked and what might be done to improve it.
