Solution:
Total number of seats in the plane = 57
From MSY to DFW = 44 passangers
From DFW to OKL = 49 passangers
From OKL to TUL = 36 passangers
From TUL to FWB = 30 passangers
From FWB to MYS = 49 passangers
So the average number of seats filled per flight
= (44+49+36+30+49) / 5
= 208/5
= 41.6
For the last 5 flights Load factor = Average number of seats filled per flight / Total number of seats in the plane
= 41.6 / 57
= 0.7298
= 72.9%
So for the last five flights the load factor was 72.9%
