A customer needs 88, 2-inch pipe connectors to complete a project. How many bags of connectors would you recommend the customer purchase if each bag includes 25 connectors?
25 to a bag? Obviously, you need three bags (75 connectors), plus another 13 bought individually. For a project of that size, I would buy a couple of extras (90 total), in case anything goes wrong with any of the connections. But it might turn out to be cheaper to buy four bags (if the price for a bag is much less than the price of 25 bought individually), in which case it would be smarter to buy four bags.
four, three is not enough. But 2 couplings of any kind should be sold singly.
