The answer is 36 because 50% is half 18 times 2 is 36.

Remember:  50% means 1/2.  So, if 18 is 50%, or 1/2, of a number, the number must be double 18.

18 x 2 = 36

18 is 50% of 36.

den301095 [7]

Answer:

4 players and 1 instructor

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.
