Math Problem Statement
Suppose that the weight (in pounds) of an airplane is a linear function of the total amount of fuel (in gallons) in its tank. When graphed, the function gives a line with a slope of 6.0. See the figure below. With 50 gallons of fuel in its tank, the airplane has a weight of 2,400 pounds. What is the weight of the plane with 78 gallons of fuel in its tank?
