Question

anonymous · Answer

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.
