9. Four friends want to rent a moon bounce facility for a party. They agree to share the cost equally. The rental charge is n dollars per hour regardless of how many people are using the facility. The difference in the cost when 5 people share the cost to rent the facility for two hours and when only 4 people share the cost to rent the facility for two hours is $18.75 per person. Write an equation in terms of n, that models this situation. Solve the equation for n, and explain what the value your find for n represents. Show your work.
