The first and only stop of the flight can be Boise, Omaha or Chicago. This means there are 3 possibilities where to stop. From thee the flight connects to New York City, either to La Guardia or to JFK Airport. 1 possible route: Seattle-Boise-La Guardia <span>2 possible route: Seattle-Omaha-La Guardia </span><span>3 possible route: Seattle-Chicago-La Guardia </span><span>4 possible route: Seattle-Boise-NYC </span><span>5 possible route: Seattle-Omaha-NYC </span><span>6 possible route: Seattle-Chicago-NYC </span> Or in other words: There are two airports where the flight can arrive and for each of them there are three possible routes. So, in total there are 2*3=6 possible routes.
The answer to your problem would be 400 because to find the answer you need to multiply 120 by .3 to get the answer because 3 % means per 100 and that is why you make it .3 hope i help.
