A medical supply company often holds events to promote an arthritis product. At these events, the company gives attendees a package of products and a snack. In addition, the owner of the venue charges the organizer a fixed service value for each person who attends. For this reason, the company has to charge each participant a value for the entrance to the event.

The company knows that at these events, for some strange and unexplained reason, 35% of the elderly always arrive, 25% of doctors belonging to the College of Physicians and the rest are the general public. As is well known, senior citizens have a 50% discount on the ticket price and do not pay VAT, and members of the College of Physicians receive a 10% discount.

It is required to make a system (program) that calculates the data of an event. For this, the user must enter the system, the data of the total number of attendees, the price of the ticket (without VAT) and the cost of product-snack-service that is spent per attendee.

The program should calculate:

the total revenue from ticket sales,

the VAT to be paid,

the total cost (expense) and

the value that the company gained or lost in carrying out the event.

VAT is 12%.
