MatLab code. Thank you

You and your partner are programming software for a delivery company. The employee inputs the weight of the package and the distance to be delivered. 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 thereof over two pounds. If the package weighs more than 70 pounds, a $15.00 excess weight surcharge is added to the cost. No package over 100 pounds will be accepted. Additionally, the cost of delivery is $0.15 per mile for the first 50 miles, and $0.05 per mile thereafter. Write a program that accepts the weight of a package in pounds and distance to delivery in miles, and computes the cost of mailing the package. Be sure to handle the case of overweight packages
