In Chapter 1, you created two programs to display the motto for Marshall's Murals. Now write a program named MarshallsRevenue that prompts a user for the number of interior and exterior murals scheduled to be painted during the next month. Compute the expected revenue for each type of mural. Interior murals cost $500 each, and exterior murals cost $750 each. Also display the total expected revenue and a statement that indicates whether more interior murals are scheduled than exterior ones. An example of the program is shown below: Enter number of interior murals scheduled 3 Enter number of exterior murals scheduled 1 3 interior murals are scheduled at $500.00 each for a total of $1,500.00 1 exterior murals are scheduled at $750.00 each for a total of $750.00 Total revenue expected is $2,250.00 It is True that there are more interior murals scheduled than exterior ones. 18 int, Parse(Console we adLine()); 19// compute interior murals revenue 20 int_revaint_num* 500 ; 21 / feompute exterior murals revenue 22 ext_reva ext num+76e; 23// calculate total expected revenue 24 tot. reveint _ev + ext_revi 26//print all fenexated revenues 20 Console.
