Answer:
10 tickets
Explanation:
The difference in club fee is $30. The difference in ticket price is $3. It takes 30/3 = 10 tickets to make up the difference in club fee.
__
The cost of 10 tickets for "a movie club" is $30 + 10×8 = $110.
The cost of 10 tickets for "another club" is $11×10 = $110.
The two clubs have equal costs for purchase of 10 tickets.
