Question 366881: A carpenter charges a set fee for each job in addition to his hourly charge. If he bills a cutomer $125 for ajob which takes him 3 hours and bills a second customer $200 for a 6 hour job, how much would he charge for a job that takes him 8 hours? Answer by ptaylor(2198) (Show Source):
You can put this solution on YOUR website! Let x=set fee and y=hourly charge
x+3y=125----eq1
and
x+6y=200----eq2
subtract eq1 from eq2:
3y=75
y=$25 per hour----hourly charge
substitute y=$25 into eq1:
x+75=125 or
x=$50 set fee
CK
50+75=125
and
50+6*25=200
Hope this helps---ptaylor
