The application should calculate and display the miles per gallon obtained for each tankful and display the total combined miles per gallon obtained for all tankfuls up to this point. Additionally, the application should categorize and display the consumption rate of gasoline as follows: Low, if the total miles per gallon is greater than 30. • Normal, if the total miles per gallon is between 20 and 30. High, if the total miles per gallon is less than 20. All averaging calculations should produce floating-point results. Display the results rounded to the nearest hundredth. c# program
