A baseball team has $6 million to hire new players for the next season, and each new win is expected to increase revenue in $1 million. The estimated Wins Above Replacement (WAR) of players A, B and C, who play in different positions, are 6, 3 and 3, respectively. If the salaries requested by the three players are $6 million, $2.5 million and $2 million, what player(s) should be hired? A. Player A, because is the one that contributes with...
