Answer:
$213.27
Step-by-step explanation:
12 x $.89 = $56.68, so that is the cost of gas for their first stop.
17 x $4.72 = $80.24, so that is the cost for the second stop for gas.
15 x $5.09 = $76.35, so that is the cost of gas for their final stop.
Now we add these all together for our final answer.
$56.68 + $80.24 + $76.35 = $213.27. That is the total cost on gas for the trip.
