While shopping, Dawn finds a backpack that she likes on the sale rack. Its original price is $60, but everything on the rack comes with a 30% discount. Dawn also has a coupon for 15% off of
her total purchase.
Dawn says, "Thirty percent and fifteen percent make forty-five percent and 45% of $60 is $33,
so it will cost $33."
Is Dawn correct? Explain why or why not. Be sure to support your reasoning with a
mathematical model.

No, Dawn is not correct.

Step-by-step explanation:

I cannot provide you with a model, but the 30% discount should be applied first. 60*(70/100) = 42. Therefore, after the 30% discount, the cost will be $42. After that, Dawn should use her coupon. It will then get you 42*(85/100) = 35.70. Therefore, she would pay $35.70.
