Over the weekend, Brady and Jake drove to Key West go scuba diving. Now they're preparing to go home. Brady needs gas for his jeep, which gets 21 miles per gallon for gas mileage. When he stops at a gas station, he already has 5 gallons of gas in his tank. He buys more gas for $1.40 per gallons. If Brady spends $19.50 on gas, what is the total distance the boys can travel? Round, to the nearest tenth

His car gets 21 mpg (miles per gallon). With 1 gallon he can drive 21 miles. For example, with 10 gallons, he can drive 21 mpg * 10 gal = 210 miles.

He bought $19.50 worth of gas at $1.40 per gallon.

$19.50 / ($1.40/gal) = 13.93 gal

He already had 5 gal of gas in his tanks, so now he has

5 gal + 13.93 gal = 18.93 gal

With 18.93 gal, he can drive

18.93 gal * 21 mpg = 292.5 miles
