Question 1147133: Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 18 gallons of fuel, the airplane weighs 2199 pounds. When carrying 50 gallons of fuel, it weighs 2375 pounds. How much does the airplane weigh if it is carrying 54 gallons of fuel?

So, by the given information, a 32 gallon increase is equivalent to a 176 pound increase. So a increase of 4 gallons is equal to a 176/8=22 lb. increase. So 2375+22=2397 lb.
