2.5 (20 points) The cost of sending a package by an express delivery service is $15.00 for the first two pounds, and $5.00 for each pound or fraction there of over two pounds. If the package weighs more than 50 pounds, a $15.00 excess weight surcharge is added to the cost. If the package weighs more than 70 pounds, a $30.00 excess weight surcharge is added to the cost. No package over 100 pounds will be accepted. Write a program in a script file that accepts the weight of a package in pounds and computes the cost of mailing the package. Be sure to handle the case of overweight packages. The program asks the user to enter the number of weight. The program then displays the cost. Save your program a script file named hw0205.m. Test your program on four cases for 1 pound, 45 pounds, 90 pounds and 110 pounds. Show your MATLAB code and the three results. into
