A university had forecasted its new enrollment at 2,000 students and ordered 2,200"Inspiring Minds" unisex t-shirts at a bulk price of $13.10 each,to be included in each student's welcome package (the extra 200 were an initial safety order). The final enrollment is 2,500 students, and now the missing 300 t-shirts must be backordered at an increased price of $21.54 each.What is the university's regret to not have chosen an initial safety order of 500?
