    Answer:

    357 passengers

    Step-by-step explanation:

    \frac{x}{420}=\frac{85}{100} (The \frac{85}{100} is 85% of the 100% people because 15% is missing)

    When you cross-simplify you get: \frac{x}{21}=\frac{85}{5} which is \frac{x}{21}=17

    Finally, multiply 17 by 21 to get x.

    Therefore, x=357
