Joe is in charge of purchasing office supplies and his budget is $175.00. paper is $21.99 a box, toner cartridges are $52.90 each, and folders are $0.99 each. all office supplies are 20% off. if joe needs to buy 3 boxes of paper and 2 toner cartridges, how many folders can he buy?

21.99 * 3 = 65.97 * 0.80 = 52.78 for paper

52.90 *2 = 105.80 *0.80 = 84.64 for toner

52.78 + 84.64 = 137.42 total

175-137.42 = 37.58 he can spend on folders

0.99*0.80 = 0.79 each folder

37.58/0.79 = 47.57
