<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?
<bot>: How many minutes does it take Melissa to replace the buckle and even out the heel? ** First find the total time Melissa spends per shoe: 5 minutes + 10 minutes = <<5+10=15>>15 minutes
How many minutes does Melissa spend on this project total? ** Then double that amount because there are 2 shoes: 15 minutes * 2 = <<15*2=30>>30 minutes
