What is the hourly charge for his repair services?
A

B
$11 an hour
C
$75 an hour
D
$82.50 an hour
The information provided does not specify the hourly charge for repair services.
hour: 0,2,4,6
charges:15,165,315,465
To find the hourly charge for repair services, we can look at the difference in charges for each hour:
Hour 2 - Hour 0 = $165 - $15 = $150
Hour 4 - Hour 2 = $315 - $165 = $150
Hour 6 - Hour 4 = $465 - $315 = $150
The difference in charges for each hour is consistently $150. Therefore, the hourly charge for repair services is $150.
None of the given options, A, B, C, or D, matches this answer.
