With 48 gallons of fuel in its tank, the airplane has a weight of 2378.4pounds. What is the weight of the plane with 81gallons of fuel in its tank?

Question

The function gives a line with a slope of 5.8.

Answer 1

if slope =5.8

W= P+5.8F

2378.4 = P =5.8(48) = P +278.4

Plane Weight = 2378.4 -278.4 = 2100 pounds

Total Weight with 81 gallons = 2100+5.8(81) = 2100+469.8 = 2569.8 pounds
