Question

Charles is taking a weekend trip to Los Angeles, CA. He can drive his old 1991 car, which gets 20 miles per gallon, or he can rent a car that gets 35 miles per gallon on a special weekend rate. His trip will be 350 miles round trip. If he drives his old car, and the cost per gallon of gas is $2.89, what is the cost of gasoline on his trip?

Answer 1

$50.58

Step-by-step explanation:

Sine Charles's old car only gets 20 miles per gallon and the round trip will be 350 miles, he will use 350/20 = 17.5 gallons.

Since each gallon costs $2.89, he will spend in gasoline a total of = 17.5 gallons x $2.89 per gallon = $50.58

If he drove the other car he would have spent 10 gallons x $2.89 = $28.90 in gasoline
