Question

The average weight of the passengers of an airline has increased from 150 pounds in 2000 to 170 pounds in 2010. If an airline used to transport 270 passengers in a plane in 2000, and the total passenger weight is fixed, approximately how many passengers can travel with the same plane in 2010?

Answer 1

Average weight increased from 150lbs in 2000 to 170lbs in 2010.

In 2000, the airline transported 270 passengers, with an average weight of 150lbs:

270passengers*150lbs = 40,500lbs

In 2010, the airline can still only hold 40,500lbs, but the average weight is 170lbs:

40,500/170 = 238.23, so you can only hold approximately 238 passengers.

Hope that helps!
