Newman has decided he is going to pursue the "bottle deposit scheme". He and Kramer will collect cans and drive them to Saginaw Michigan where they will get the refund per can. The refund amount per can has just increased for the upcoming President’s Day weekend. The refund is now $0.20 per can. Newman knows with the short amount of time he has that only two options are available: the Uhaul plan and the Mailtruck plan. The underlying scheme is the same but the costs have shifted a bit.

The Uhaul plan consists of the following costs:
- fixed rental costs for the Uhaul of $400
- fixed gasoline costs of $1.99 a gallon for the 1,400 mile roundtrip excursion and they can expect to get about 17 miles per gallon with the Uhaul
- variable costs of $0.02 per can but the Uhaul can easily handle 4000 cans before these costs kick in (i.e., Newman gets 4000 cans free before the variables costs start)

The Mailtruck plan consists of the following costs:
- fixed rental costs for the Mailtruck of $0 [he gets it free for being a Postal Carrier]
- fixed gasoline costs of $1.99 a gallon for the 1,400 mile roundtrip excursion and they can expect to get about 13 miles per gallon with the Mailtruck
- variable costs of $0.06 per can as the Mailtruck is older and needs TLC so the variable costs are higher than the Uhaul --- In addition, it can only handle 2000 cans before these costs kick in (i.e., Newman only gets 2000 cans free before the variables costs start)

The variable costs for both plans consist of wear and tear on the vehicle as more cans are loaded in (i.e., oil, radiator fluid, etc.) and charges through the toll-ways (e.g., the Uhaul gets a different rating and pays less than the Mailtruck when passing through toll-ways). Answer the following questions based on a comparison of costs between the two plans.

a. If Newman expects to collect around 6000 cans, which plan should he select?
