In my chemistry class, 28 students are given 3 pens. If there are 8 pens in one package, priced at $1.88 per package, what is the total cost of giving away pens?
28 students are each given 3 pens....28 * 3 = 84 pens 8 pens in 1 pack.....84/8 = 10.5....so 11 packs were bought at 1.88 per pack....11 * 1.88 = $ 20.68 <==
