Answer:
90 at the least. You will have 1 empty seat.
Step-by-step explanation:
Simple.
(If Have) use a calculator to divide 1,284 by 14.
You will have the answer 91.7142857143.
However you can't have the number since it's a percentage so what you want to do is take away the 1.
P.S trust me it will be weird to have 1.7ths of a human.
