Monic and Matt are moving crosscountry using a rented truck. Monica will drive the truck, and Matt will drive their car. After travelling 285 miles, they stop for gas, which costs $3.49 per gallon. Both vehicles start with a full tank of gas. Monica putss 22.8 gallons of gas in the truck. Matt puts 9.5 gallons of gas in the car. About how much will they spend, altogether, to travel 1,800 miles?

(22.8+9.5)(1800/285)(3.49) = $711.96
