Question

An airplane flight has 207 seats. the probability that a person who buys a ticket actually goes on that flight is about 90%. if the airline wants to fill all the seats on the flight, how many tickets should it sell?

Answer 1

Answer:

230 tickets

Step-by-step explanation:

Create a proportion using the given information:

Let's set x equal to the number of tickets that need to be sold.

$\frac{207}{90} =\frac{x}{100}$

Cross multiply and you get:

$90x=20700$

Then divide both sides by 90 to get:

$x = 230$

This means that 230 tickets need to be sold in order to fill all of the seats on the flight.
