Joe is taking a trip to see his grandmother. He will drive a total of 240 miles round trip. He expects to take the highway and travel there on Thursday. Going to her house he thinks he'll average about 60 miles per hour. Unfortunately he will have to come home on Sunday, when traffic is bad, so he'll probably only be able to average 50 miles an hour coming home. His car gets good gas mileage so he thinks he'll get about 40 miles/gallon for the entire trip. If gas costs $3.59 per gallon, how much will Joe spend on gas to visit his grandmother? (When entering your answer, do not include the dollar sign, only the decimal number.)
