Step-by-step explanation:
Let x = the hourly rate of the first mechanic and
y = the hourly rate of the second mechanic.
As far as the equation goes for the total amount charged:
10x + 5y = 950
As far as the equation goes for the sum of the 2 mechanics' rates:
x + y = 125
Solve the first equation for either x or y. I solved for y:
y = 125 - x
Now plug that into the first equation for y to get:
10x + 5(125 - x) = 950 and
10x + 625 - 5x = 950 and
5x = 325 so
x = 65
The first mechanic charges $65 per hour and the second mechanic charges
y = 125 - 65 so
the second mechanic charges $60 per hour.
