Divide the cost by the number of items to find the price of each item.

$40.80 / 250 = ?

$18 / 100 = ?

Thank YOU Ms. Sue!!! The difference is 2 cents per item and, if I may steal another minute from you, I wonder if it pays to get the smaller quantity at 0.18? Or the larger quantity at 0.163? Thanks again so much! Aderosa

It depends upon how you define cheaper. IF you mean the cheaper to purchase, obviously $18 is cheaper than $40.80. On the other hand, 40.80/250 = 0.163 per item while the other one costs 18/100 = 0.18 per item. So on a per item basis, the cheaper is the one that costs 40.80 for 250 of the items.

Whether to pay $0.18 or 0.163 per item depends on the item. Is the item perishable or have a relatively short shelf life? Do you want to store 250 items? For instance, although I intend to use detergent for many years to come, do I really want to store 250 ounces of detergent? Is the container too big to easily handle?
