At danielle’s clothing boutique, if an item does not sell for eight weeks, she marks it down by 15%. if it remains unsold after that, she marks it down an additional 5% each week until she can no longer make a profit. then she donates it to charity. rafael wants to buy a coat originally priced $150, but he can’t afford more than $110. if danielle paid $100 for the coat, during which week(s) could rafael buy the coat within his budget? justify your answer.
