1. Assume that there is a fuel price-war going on in the HCMC area, 25
miles one way from where you normally purchase fuel. The current
price in HCMC is $0.50 less than the price of $3.65/gal in VUNG T AU.
You own a CAFÉ-compliant 2009 model-year car (23.1 miles/gallon)
with a 15gal tank. Does it make economic sense to make the trip solely
to purchase fuel?
2. Perform the same analysis as in Q-1 if: (a) you own a CAFÉ-compliant
2010 model year SUV (23.5 mpg) with a 22 gal tank; (b) you own a 2011
Prius with a 11.9 gal tank (32.4 mpg)
