To celebrate the holiday season this year, Six Flags has created an extreme six-lane, tubing hill with real snow called the “Superman’s Awesome SNOW Tubing Ride.”  The cost of each ticket for one day is $35.  The number of tickets purchased by groups is given by the domain {3, 8, 12}.  Which would be a reasonable range for the total cost of the tickets the groups would pay? 

• {3,8,12}

• {105,280,420}

• {3,8,12,105,280,420}

• {38,43,51}
