Your friend works at the post office. Express delivery service is $20 for the first 4 pounds and $3 for each additional pound thereof over four pounds. If the package weighs more than 90 pounds, a $4 extra surcharge is added to the cost. No package more than 140 pounds the post office accepts. You need to write a program that accepts a weight of a package in pounds and computes the cost of a mailing the package. Do not forget to handle the case of overweight packages. please use MATLAB
