###Human: 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?, ### Assistant: 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 
 So the answer is :  30
