Final answer:

Alanna's mistake is multiplying 12 and 4 instead of multiplying 12 and 4c in Step 2. The correct steps to solve the equation are explained.

Step-by-step explanation:

Alanna's mistake is in Step 2. She incorrectly multiplied 12 and 4 instead of multiplying 12 and 4c. To correct the mistake, we need to rewrite the equation as 4c=12 and then multiply both sides of the equation by 4. This gives us 4c=12*4c. Simplifying further, we get 4c=48c. Now, dividing both sides of the equation by 4, we find c=48.
