Answer: NO (222 SEATS IS LESS THAN 255 SEATS )
Step-by-step explanation:
1 first-class section
The first-class section has 14 seats.
5/7 are being used = 5/7 * 14 seats = 10 seats
Unused seats = 14 seats - 10 seats = 4 seats
1 business-class section
The business-class section has 64 seats.
5/16 are being used = 5/16 * 64 seats = 20 seats
Unused seats = 64 seats - 20 seats = 44 seats
4 economy-class sections
Each economy-class section has 108 seats.
Each economy-class section has 108 seats.
5/9 in each section are being used = 4 * ( 5/9 * 108) = 240 seats
Unused seats in 4 economy - class section = 4*108 - 240 = 192 seats
Total seats in an airbus = 1 first-class section + 1 business-class section + 4 economy-class sections
Total seats in an airbus = 14 + 64 + 432 = 510 seats
used seats in an airbus = 1 first-class section + 1 business-class section + 4 economy-class sections
used seats in an airbus = 10+20 + 192 = 222 seats
half of total seats = 510/2 = 255 seats
used seat = 222 seats
222 seats < 255 seats
Thus NO
