Final answer:
Caleb earns the same rate of $8.50 per hour at both the carwash and the restaurant when comparing his earnings per hour.
Step-by-step explanation:
To compare Caleb's rate per hour at the carwash and the restaurant, we calculate the dollars he earns per hour at each job. At the carwash, Caleb earns $34 for 4 hours of work, so we divide the total dollars earned by the total hours worked to find the rate per hour:
Rate at Carwash = Total Dollars Earned at Carwash / Total Hours Worked at Carwash
= $34 / 4 hours
= $8.50/hour
Similarly, at the restaurant, Caleb earns $51 for 6 hours of work. We use the same approach to find the rate per hour:
Rate at Restaurant = Total Dollars Earned at Restaurant / Total Hours Worked at Restaurant
= $51/6 hours
= $8.50/hour
Caleb earns the same rate of $8.50 per hour at both the carwash and the restaurant.
