In a cinema hall the chairs are ordered in a rectangle shape in r rows and c columns. There are three types of screenings with tickets of different prices:
- Premiere – a premiere screening, with price 12.00 levs.
- Normal – a standard screening, with price 7.50 levs.
- Discount – a screening for children and students on a reduced price - 5.00 levs.
Write a program that enters a type of screening (string), number of rows and number of columns in the hall (integer numbers) and calculates the total income from tickets from a full hall. The result has to be printed in the same format as in the examples below - rounded up to 2 digits after the decimal point.
