Answer:
$50 and $115
Step-by-step explanation:
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:
[tex](x*15)hour+(165-x)*5 hour=1325[/tex]
Solving for x to get:
[tex]15x-5x+825=1325[/tex]
[tex]10x=500[/tex]
[tex]x=50[/tex]
So the rate charged per hour by one mechanic is $50 and for the other mechanic = [tex](165-50)=[/tex] $115.
