<u>Answer:</u>
$50 and $115
<u>Step-by-step explanation:</u>
We know that,
the sum of the two rates = $165 per hour
Let x and (165 - x) represent the $/hour of the 15hr and 5hr mechanics respectively.
Then combining their charges together to get:
Solving for x to get:
So the rate charged per hour by one mechanic is $50 and for the other mechanic = $115.
