You can put this solution on YOUR website! F=daily fee; M=miles
3F+300M=$129 Multiply each side by 2
6F+600M=$258
5F+600M=$240 Subtract
F=$18 ANSWER 1: The daily fee is $18.
3F+300M=$129
300M=$129-3F
300M=$129-$54
300M=$75 Divide each side by 300
M=$0.25 ANSWER 2: They charge $0.25 a mile.
CHECK:
5F+600M=$240
5($18)+600($0.25)=$240
$90+$150=$240
$240=$240
