Solution Alternatives
- Input product information and price
- Input quantity for the product
- Multiply price times quantity = total price for each product
- Sum all of the total prices
- Multiple the sum of total prices by sales tax to determine sales tax to add
- Add the sum and the sales tax adder for the final amount due
- Manually calculate on a calculator and hand total written on a piece of paper
- Allow Point of Sale (POS) scan the product that inputs price and select quantity. Sales tax is part of the application based on the location of the purchase. POS outputs a receipt with all computations and final total
