Math, microeconomics or criminal justice
W = A+GF = total weight = airplane weight plus gallons time weight of fuel per gallon
1988 = A + 16F
2164 = A + 48F
2164-1988 = 32F
176 = 32F
F = 176/32 = weight of a gallon of fuel = 5.5 pounds per gallon
1988 = A + 16(5.5) = A + 88
A = 1988-88 = 1900 pounds = weight of the airplane
2164 = 1900 + 48F
48F = 2164-1900 = 264
F = 264/48 = 132/24 = 66/12 = 33/6 = 5.5 pounds per gallon of fuel
