PROBLEM 6:
A hotel has a pricing policy as follows:
2 people: $85 3 people: $90 4 people: $95 Additional people: $6 per person

If the customer is staying on company business, there is a 20% discount. If the customer is over 60 years of age, there is a 15% discount. A customer does not receive both discounts. Given the above data, Write a C Program to print the cost of the room.
