Shopping Basket Discount

Calculate the total price of a shopping basket. Items in the basket have a unit price and quantity.

For example:

• price $10, quantity 5
• price $25, quantity 2
• price $9.99, quantity 6

If you buy in bulk, you get a discount:

• If total value > $100, apply a 5% discount
• If total value > $200, apply a 10% discount
