Make a program that can be used to determine the self$-$cleaning of the carpet. Washing costs $6\mathrm{.}00$ euros per square metre from $0-16$ and from $17-23$ washing costs $7\mathrm{.}00$ euros per square metre.

Make two functions for the solution in addition to the function for the button

CalculateThis function calculates the price per square metre for washing. The function takes the time of day as a parameter and returns the price per square metre $(6\mathrm{.}00$ or $7\mathrm{.}00).$

The calculatePrice function calculates the price of washing a carpet. The function takes as parameters the width, length and price per square metre of the carpet and returns the price of the wash.

Note: The above functions must be named exactly as their names are given. You cannot change the names of the functions in your solution or the code will not test in Viope. You are free to choose the names of the function parameters.

If the assignment contains only a function for a button, the maximum number of points you can get for the assignment is three.
