Barbara must buy four new tires for her car. She is considering buying tires that are $25 apiece more than her regular brand, because the higher priced tires are supposed to increase the miles per gallon by 20%. If the tires are good for 48,000 miles and she drives an average of 1,000 miles per month, gas costs $2.50 per gallon over the next 4 years, and the car gets 30 miles to the gallon now (on the old tires), should she purchase the more expensive tires?

• Yes, because she will save about $660 dollars in gas over the four years but the new tires will only be $100 more.
• Yes, because Barbara will save about $560 dollars in gas over the four years but the new tires will only be $100 more.
• No, because she will only save about $60 dollars in gas over the four years and the new tires will be $100 more.
• No, because she will only save about $90 dollars in gas over the four years and the new tires will only be $100 more
