Biking Dimensional Analysis
Given:
bike price = 500 dollars
gas price = 3.50 dollars/gal
gas mileage = 19 miles/gal (

)
commute distance (round trip) = 10 miles
500 dollars * (1 gal/3.50 dollars) * (19 miles/1 gal) * (1 day/10 miles) = 271.4 days
Based on that, I need to ride my bike 272 days to pay for my bike.
