Answer:
then more than half seats in plane are being used.
Step-by-step explanation:
in first class section,,
total seats =14
5/7=10/14
ocupied seats=10
in buisness class section,,
total seats =64
5/16=20/64
ocupied seats=20
in 4 economy class section,,
total seats=4 x 108=432
5/9=60/105
occupied seats = 4 x 60
=240
total seats in plane = 432
+64+14=510
total occupied seats = 240+20+10=270
half of total seats in plane =1/2 x 432=216
since 270>216
then more than half seats in plane are being used.
