%/100 X is/of 177 IS 60% of the students. so you put 60/100 and multiply 177/X 177X100=17700. Now divide that by 60 and you come up with 28.33. This obviously is not the answer so you add 28 (does not round up to 29) to 177 and you get 205.
Find what percent of $39.00 the sale price was. => 15/39*100=38.4% now subtract from 100% to get the mark down percentage. 100-38.4=61.6 Final answer: Marked down 61.6% Hope I helped :)
