Hello I really need help understanding how to do this using RAPTOR. Please send me a screenshot of how you did this on RAPTOR. Thank You

SupremeZ is a superstore that sells different items to its customers. When customers buy from the store then they are given a receipt/invoice. Create a program in RAPTOR that will calculate the total amount for an invoice. At first the program will ask how many products are there in the invoice. Then the program will take input of product price and quantity for each product in the invoice. As the items are entered, the program calculates the total of the invoice. If the calculated total is greater than $50 then the customer gets a 5% discount on the total. At the end, the program outputs i) The total for the invoice ii) If the invoice is eligible for a discount, then it shows the discounted total iii) It applies 13% HST on the total/ discounted total iv) It displays the total payable
