Which is the better buy: 6 muffins for $7.59, or one dozen muffins for $14.99?

Ok, so the 6 muffins for $7.59 compared to the one dozen of muffins for $14.99 the one dozen is the better deal 'cause if the one dozen is the double of the 6 muffins just double the amount of $ for the 6 muffins since it's 1 half of the dozen so when u double it = $7.59 * 2 = $15.18 compared to the dozen it's $14.99 which leaves the one dozen as the better buy. I hope this helps!

Is there a picture of a graph or whatever that goes along with this?
