A travel company had a contest, and Bree won a trip to seven countries. The rules are that Bree must visit the countries in the order told to her by the travel company, but she can decide to skip visiting any of the countries except the first one. So, Bree can visit a total of 1,2,3,4,5,6 or 7 countries. In how many ways can Bree organize her trip?
The answer isn't 2520 btw
