Decide whether the statement makes sense. Explain your reasoning.Jose's car gets about 20 miles to the gallon. He is thinking of buying a new fuel-efficient car which gets miles to the gallon and which costs $25,000. He reasons in this way: " I drive about 300 miles per week. Gas costs about $3.50 per gallon. That means I'll save $1365 per year on gas. That means that if gas remains at $3.50 per gallon it will be about 18 years before the car has paid for itself. I don't think I can justify buying the new car. "
