Michelle has a patty and invites 3 friends.
Each friend invites 3 other friends.
each of these friends invites 3 more friends.
Finally,each of these friends invites 3 more friends.

Friends = 3 + 3^2 + 3^3 + 3^4 + 3^5 = 3*(3^5-1)/(3-1) = 3(242)/2 = 363
Each guest at the party brings 3 gifts, with 3 bows on each gift. How many bows does Michelle get at the party?
-----
# of bows = 3*363 = 1089
