Final answer:
To find the price per dozen muffins, set up a proportion using the given information. Solve for x by cross-multiplying and dividing. The price per dozen muffins is $10.35.
Step-by-step explanation:
To find the price per dozen, we need to determine how many muffins are in a dozen. Since a dozen means 12, we can set up a proportion to solve for the price per dozen:
4 muffins / $3.45 = 12 muffins / x
To solve for x, we can cross-multiply and divide:
x = ($3.45 * 12) / 4 = $10.35
Therefore, the price per dozen muffins is $10.35.
