The club supplies 40 new balls for each player which cost $1 each. Each player pays $300 for the lessons. The club must pay each
instructor $1,000 for conducting the lessons, and there must be at least 1 instructor for every 6 players. Which amount of players and instructors meets these requirements and still gives the club a net profit?
If all 4 players pay $300 each, that equals $1,200. The instructor will get $1,000 of it. That means there is $200 left. They need 40 balls per player. Each ball is $1, so that's $40 per player. 40 x 4= 160 200-160 = 40 The club will have $40 left.
