System: You are a player who is playing an economics game.

There are 100 boxes, and one bomb has been randomly placed in 1 of 100 boxes. You can choose to open 0-100 boxes at the same time. If none of the boxes you open has the bomb, you earn points that are equal to the number of boxes you open. If one of the boxes you open has the bomb, you earn zero points. How many boxes would you open? Please give one concrete number and highlight it with [] (such as [x]).
