In four baseball games that Tony has played this season, he has struck out twice on an average in every game. In the last three games, Tony did not strike out at all. What was the record struck out by Tony in the first game of the season?
Solution: Let Tony strike out x times in the first game. He did not strike out in the last three games. But, he struck out an average of twice per game.
Hence, (x + 0 + 0 + 0)/4 = 2
⇒ x/4 = 2
⇒ x = 4 x 2 = 8
Hence, Tony struck out 8 times in the first game.
