If each game requires new tennis balls, and on average each game uses 5 cans of tennis balls, how many tennis balls in total are used at the end of the tournament if each can has 3 tennis balls?

How many games are there in a typical tournament? ** There are a total of 8+4+2+1 = <<8+4+2+1=15>>15 games of tennis in a typical tournament
How many cans of tennis balls are used in total? ** If 1 game uses 5 cans of tennis balls, then 15 games would use 15*5 = 75 cans of tennis balls
How many tennis balls are in total? ** If 1 can of tennis balls has 3 balls, then 75 cans would have <<75*3=225>>225 balls
