Question

A plane has fees for 420 passengers 15% of the seats are empty how many passengers are on the plane​

Answer 1

357 passengers

Explanation:

`(x)/(420)=(85)/(100)` (The
`(85)/(100)` is 85% of the 100% people because 15% is missing)

When you cross-simplify you get:
`(x)/(21)=(85)/(5)` which is
`(x)/(21)=17`

Finally, multiply 17 by 21 to get x.

Therefore, x=357
