An office supply store A isn’t offering copy paper for $3.00 per pack. Store B is running a special of buy two for $4.20 each and get one free. You need 12 packs of paper. Where is the best price for copy paper?
Store B, since they are two for 4.20$ while Store A has only ONE for 3.00$ meaning let’s say we’re gonna buy two packs it would be 4.20$ for Store B and 6.00$ for Store A
