The correct answer to this open question is the following.
Randy is a minor-league baseball player. His current cumulative batting average is 0.270. Randy believes that if he can raise his cumulative batting average to 0.300, he will have a chance to play in the major leagues. The correct statement is "Randy must get more than 30 hits out of his next 100 at bats in order to raise his cumulative batting average to 0.300.
What Randy must do is to improve his batting efficiency if he wants to get a good shot at Major Leagues. If he wants to get a 0.300 average, then we have to get the right percentage operation to know the exact number he needs to have. So for every 100 turns at batting, he needs a minimum of 30 hits to get the correct percentage.
