1. An investment of $1500 paid interest of $45 during a certain period. How much interest would an investment of $2000 invested at the same rate for the same length of time pay?
2. In baseball a player's batting average is the ratio of hits to the number of times he or she has batted. Thus, if the player has an average of .300, it means he or she got 300 hits out of 1000 at bats. In order to have an average of .300, how many hits would the batter have to get in 400 times at bat?
I think I have the answers to these problems but I'm not sure. Please check my answers and explain how you got the answer so I can check it against mine. Thanks!
