Before a game, Jake's batting average was exactly 0.350.  That is, the decimal expansion of the fraction $$\frac{\text{number of hits}}{\text{times at bat}}$$ is equal to 0.350. During the game, Jake bats 4 times and get 2 hits.  If Jake's batting average after the game is 0.359, how many times had Jake batted before the game? Explain.
