STUCO is having a bake sale to raise 400 riyals for a new basketball ring. Tala’s dad has some contacts with a local bakery that has agreed to sell them each cookie for 1.50 riyals. The cafeteria bake sales usually sell 60-80 cookies per day. What is the percent markup that STUCO needs to charge in order to reach their goal during the bake sale?
