What is the cost of one cranberry and one banana nut muffin?

So for the cranberry muffin, for every 12 (a dozen) it's $3
Banana nut muffin: for every 12, it's $4.32
take the $3 and divide it by 12 which is $0.25 for every cranberry muffin
take $4.32 divide by 12 and you get $0.36 for every banana nut muffin
so $0.25 + $0.36 = $0.61
Therefore the answer is B

The answer would be $0.61 because you have to add up the costs of each muffin and divide it by 12 (a dozen) to get your answer, $0.61.
