A 12-pack of soda costs 5.40. A 24-pack costs 9.60. Which pack has the lower price per can, and what is that price?

Find the price per can for each pack. The 12-pack costs $\frac{5.40}{12}=0.45$ dollars per can. The 24-pack costs $\frac{9.60}{24}=0.40$ dollars per can. The 24-pack has the lower price per can, at $0.40, choice G. Choice F names the 12-pack as the better deal, even though its unit price is correct. Choice H pairs the 24-pack with the wrong price, $0.45. Choice J pairs the 12-pack with $0.40, which is the 24-pack's price. A larger package is not always cheaper per unit, so always compute the unit price.
