Call the weght of the first truck "

". We then know that the truck after that is 2 tons more, and the next and the next. i.e:



We also know that total is 32 tons. 





Therefore the trukcs weigh 5,7,9 and 11 tons for a total of 32 tons.
Converting to pounds, the trucks weigh 10,000, 14,0000, 18,0000 and 22,000 pounds. 
 
        
        
        
<u>Answer:</u>
$50 and $115
<u>Step-by-step explanation:</u>
We know that,
the sum of the two rates = $165 per hour

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.
 $115.
