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
6.2
. See the figure below.
With
49
gallons of fuel in its tank, the airplane has a weight of
2403.8
pounds. What is the weight of the plane with
75
gallons of fuel in its tank?
