Menu 1 - Drivers are concerned with the mileage obtained by their automobiles. One driver has kept track of several tanks of gasoline by recording miles driven and gallons used for each tank. Develop a program using a while loop that will input the miles driven and the gallons used for each tank. The program should calculate and display the miles per gallon obtained for each tank. After processing all input information, the program should calculate and print the overall miles per gallon obtained for all tanks.

Menu 2- People in sales frequently earn a base salary and commission on their sales. A company has asked you to write a program to estimate the payroll for the week given a persons sales. The sales force earns a base salary of $300 per week plus 12% of their total sales for the week. Since each department has a different number of employees, use a while loop to allow the user to exit the program by entering an employee number less than 100 when they have completed.
