Give the step-by-step reasoning process and then the final answer. Melissa is repairing her shoes. For each shoe, it takes her 5 minutes to replace the buckle and 10 minutes to even out the heel. How many minutes does Melissa spend on this project total?
First find the total time Melissa spends per shoe: 5 minutes + 10 minutes = 15 minutes. Then double that amount because there are 2 shoes: 15 minutes * 2 = 30 minutes.
The final answer: 30.
