orlando likes baseball. He's a good fielder, but he wants to improve his batting average. currently .200 (or 20%) for the first part of the season. he practiced a lot with a friend and managed to hit 10 out of 20 times that he was up to bat that season.

Suppose Orlando's batting average at the ened of the season is 30% How many hits did he get during the earlier part of the season?(when his average was 20%)
