You can put this solution on YOUR website! .
T=total;F=fixed fee; R=hourly rate; x=number of hours
F+xR=T
F+6R=$242
F+9R=$338 Subtract equation from above.
-3R=-$96 Divide each side by -3
R=$32 His hourly rate was $32.
F+6R=$242
F+6($32)=$242
F+$192=$242
F=$50 His fixed fee was $50
For 11 hours(x=11):
F+11R=T
$50+11($32)=T
$50+$352=T
$402=T ANSWER: If he works eleven hours, he makes $402.
