Answer:
(a)
The equilibrium price is $75 per club
The equilibrium quantity is 75000 clubs
(b)
A charge a price of $50 per club. This would result in a surplus of 25000 clubs
Explanation:
Given
--- The demand function
--- The supply function
Solving (a): The equilibrium price and quantity
To do this, we equate both functions
This gives:
Collect like terms
Make P the subject
---The equilibrium price
Substitute 75 for P in
---- The equilibrium quantity
Solving (c): When the price is changed to $50
This means that: 
The quantity demanded will be:
Subtract the equilibrium quantity from to get the shortage/surplus
<em>Since the change is positive, then there is a surplus.</em>
