6) A plane takes off from New York with 72 of the 90 seats occupied. What percentage of seats are not occupied?

1. 20%
2. 22%
3. 24%
4. 26%

First we must identify the number of seats that were not occupied: Total – occupied = not occupied. 90 – 72 = 18. Then we can work out the percentage: Percentage = (Not Occupied Seats)/(Total Seats) X 100 = 18/90 x 100 = 20%
