Question 307782: an electrician charges a basic service fee plus a labor charge for each hours of services. A2 hour job costs $74, and a 3 hour job costs $96. Find the electrician's basic service fee. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let the basic charge be x
let the hourly charge be y
x+2y= 74
x+3y=96
subtract the equations
x+2y-x-3y= 74-96
-y= -22
y= 22
Hourly charge = $22
plug the value of y in the above equation
x+2y = 74
x+44=74
x=30
The basic charge = $30
