The original price for a case of paper is $12.88. The case of printer paper is on sale for 0.5 times the original price. How much will Alison spend on 5 cases of printer paper if she buys them on sale?
divide the original price by 2 since it is half off. that gives you 6.44. so you would multiply 6.44 by 5, since allison wants 5 cases. that gives you 32.20 dollars
