Question 1099590: 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
10
gallons of fuel, the airplane weighs
2158
pounds. When carrying
25
gallons of fuel, it weighs
2245
pounds. How much does the airplane weigh if it is carrying
35
gallons of fuel? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying
10
gallons of fuel, the airplane weighs
2158
pounds. When carrying
25
gallons of fuel, it weighs
2245
pounds.
===================
15 gallons adds 87 pounds --> 87/15 = 5.8 pounds/gallon
======================
How much does the airplane weigh if it is carrying
35
gallons of fuel?
Adding 10 gallons adds 58 pounds.
2245 + 58 = 2303 pounds
