there are three metro buses. Ask the user to enter the number of passengers each bus ferries. Call a function that takes the number of passengers for each bus and returns the total number of passengers. Then pass the total number of passengers to another function that calculates and returns the total fare earned. Assume that each passenger is charged $2.50 Then send the total fare earned to another function which deducts %50 of the total fare as operating cost and returns the remaining as net profit. display all relevant data at the end. Please note that this must be implemented using functions.
