Mark Must Buy Four New Tires for His Car

Multiple Choice

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

A) Yes, because Mark will save about $660 dollars in gas over the four years but the new tires will only be $100 more.
B) Yes, because Mark will save about $560 dollars in gas over the four years but the new tires will only be $100 more.
C) No, because Mark will only save about $60 dollars in gas over the four years but the new tires will only be $100 more.
D) No, because Mark will only save about $90 dollars in gas over the four years but the new tires will only be $100 more.
