Final answer:
After calculating the hourly wage for both individuals, Harry earns $12 per hour and Peter earns $11 per hour, which means Harry earns more per hour than Peter.
Step-by-step explanation:
To determine who earns more money per hour, we need to calculate the hourly wage for both Harry and Peter by dividing the amount of money they make by the number of hours they work. For Harry, we divide his earnings by the time to find his hourly rate: $36/3 hours = $12/hour, $72/6 hours = $12/hour, $108/9 hours = $12/hour. For Peter, we do the same: $44/4 hours = $11/hour, $88/8 hours = $11/hour, $132/12 hours = $11/hour. These calculations show that Harry earns $12 per hour while Peter earns $11 per hour, meaning that Harry earns more money per hour than Peter.
