A store is offering a sale of 30% off all items. What is the price of a $24 shirt after the discount? Round answers to two decimal places. A customer paid $16.99 for a shirt that normally sells for $19.99. What percent discount did the customer receive? Round your answer to the nearest percent. A customer and a sales person are arguing about a promotion and a coupon applied after the promotional discount. The promotion is a 20% discount on all items in the store. The coupon is an additional 10% off of the order. The customer claims the 20% discount should be made before the 10% discount. The sales person claims it does not matter which order to give the discounts. Who is correct and why (make sure you prove your claim and include relevant mathematical calculations - I am a skeptic and will doubt your answer unless you have enough details to prove your conclusion).
