Using the following table, write a program that reads a code and the amount of an item. After, print the value to pay. This is a very simple program with the only intention of practice of selection commands.
Input
The input file contains two integer numbers X and Y. X is the product code and Y is the quantity of this item according to the above table.
Output
The output must be a message "Total: R$ " followed by the total value to be paid, with 2 digits after the decimal point.
| Input Sample | Output Sample |
|
3 2 |
Total: R$ 10.00 |
|
4 3 |
Total: R$ 6.00 |
|
2 3 |
Total: R$ 13.50 |
