Acompany paid $72 for 2 cases of printer paper. each case contained 12 packages of paper. next month the company's office manager needs to order 180 packages of the same paper. if the price per package does not change, what would be the total cost of the next month's order?

The answer would be $540. First you find out how many packages of paper there are (12 x 2) and then divide the dollar total of the first month by that (72 / 24) to find how much each package costs, and then you multiply that answer by how many packages of paper they bought the next month (3 x 180) and that gives you the total amount of the second month :)
