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