Question

An airplane flight has 228 seats. The probability that a person who buys a ticket actually goes on that flight is about 95%. If the airline wants to fill all the seats on the flight, how many tickets should it sell?

345 tickets
240 tickets
2400 tickets
217 tickets

Answer 1

240 tickets sold

Explanation:

first, you would set up the proportion by writing
`(228)/(95) =(x)/(100)`

with "x" being the number of seats that needs to be sold

then, you would cross multiply

and you get

`95x=228*100` next, you simplify to get the inequality
`95x=22800`

then divide both sides by 95

`x=240`

so 240 tickets to fill all the seats

hope this helps ;)
