17. Two coaches have organized a hockey school for forwards and defensemen. The strength of this hockey school is the amount of personal time given by the coaches to individual players. Each forward will
receive 10 minutes/day with coach A and 20 minutes/day with coach B. Each defenseman will spend
20 minutes/day with coach A and 10 minutes/day with coach B. Coach A can work a maximum of
400 minutes/day and coach B can work a maximum of 380 minutes/day. What is the maximum
number of hockey players that can be enrolled in the hockey school if they are to receive this kind of
personal attention? How many of each kind of player can be enrolled?
