Have you ever heard of Chamberlain's formula, which claims to be a model that tells you how many years you should drive your present car before you buy a new one? If y is this number of years, then Chamberlain's formula reads GMC (G - M)DP where G is the new car's gas mileage, M is your present car's gas mileage, C is the cost in dollars of the new car, D is the number of miles you drive in a year, and P is the dollar price of gasoline per gallon. y = Suppose the new car's gas mileage is 36 mi/gal, the old car's gas mileage is 16 mi/gal, the price of the new car is $23,000, you drive 10,000 mi/year, and the cost of gasoline is $4.00/gal.
