Internet Lite Corporation is an Internet service provider that charges customers a flat rate of $7.99 for up to 10 hours of connection time. Additional hours or partial hours are charged at $1.99 each. Write a function charges that computes the total charge for a customer based on the number of hours of connection time used in a month. The function should also calculate the average cost per hour of the time used (rounded to the nearest cent), so use two output parameters to send back these results. Write a second function round_money that takes a real number as an input argument and returns as the function value the number rounded to two decimal places. Write a main function that takes data from an input file usage.txt and produces an output file charges.txt. The data file format is as follows: Line 1: current month and year as two integers Other lines: customer number (a 5-digit number) and number of hours used Here is a sample data file and the corresponding output file: Data file usage.txt 10 2009 15362 4.2 42768 11.1 11111 9.9 Output file charges.txt Charges for 10/2009 Customer 15362 42768 11111 Hours used 4.2 11.1 9.9 Charge per hour 7.99 11.97 7.99 Average cost 1.90 1.08 0.81
