Jason typically uses the internet to buy various items. it the total cost of all of the items ordered, at one time, is $250 or more, then the shipping and handling is free, otherwise the shipping and handling is $15 per item. design an algorithm that prompts jason to enter the number of items ordered and the price of each item. (remember cost = number of items order times price) the algorithm then outputs the total billing amount including shipping and handling. your algorithm must use a loop (repetition structure) to get the number and price of each item. write this in algorithm format not program code format.
