After sharing a meal with your long lost cousin, you remember that you have a discount card that can be applied to the cost of the meal!

- Discounted prices are always used to calculate tax (usually just 5% GST)
- Regular prices are used to calculate the tip / gratuity ( you pretend there was no discount at all ).

You’ve already calculated the tip (from the Take Your Cousin to Lunch Assignment), so you will only need to calculate the amount of the bill.

- You have a 10% off the value of the meal coupon. Determine your bill including the discount, and GST but not including the tip.
- You have a “Buy one entrée, get a second entrée of equal or lesser value for free” coupon. Determine the cost of your meal including the discount. What was the actual percent savings?
