Question

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 1964 pounds. When carrying 35 gallons of fuel, it weighs 2124 pounds. How much does the airplane weigh if it is carrying 55 gallons of fuel?

Answer 1

How much does the airplane weigh if it is carrying 55 gallons of fuel?

2433 pounds

Step-by-step explanation:

W= (2124-1964 )÷(35-10)

w= 160÷ 25

w= 6,4

w= (2331-x)÷ (42-58 )

6,4= (2331-X)÷42-58

X= 6,4*16+2331

X= 2433
