To find Craig's hourly rate for working at Job B, we need to calculate the ratio of his total salary at Job B to the number of hours he worked at Job B.
In the first week, Craig worked 30 hours at Job B and earned a total salary of $570. Therefore, his hourly rate at Job B for the first week is $570 / 30 hours = $19/hour.
In the second week, Craig worked 32 hours at Job B and earned a total salary of $594. Therefore, his hourly rate at Job B for the second week is $594 / 32 hours = $18.56/hour.
Since the question asks for the hourly rate of Job B, we can take the average of the two rates: ($19/hour + $18.56/hour) / 2 = $18.78/hour.
Therefore, Craig's hourly rate for working at Job B is closest to $19. Answer: $19.
