Step-by-step reasoning process: She will be driving 330 miles for her trip because 2 x 165 = 330. They will need 11 gallons of gas because 330 / 30 = 11. The gas will cost $33 because 11 x 3 = 33. Her total cost is $123 because 10 + 55 + 25 + 33 = 123. She needs to save $95 more because 123 - 28 = 95.
