A car gets 30 miles per gallon of gas and is driven 1000 miles per month. Gas costs \$\\$4\$ per gallon. How much will the car's owner save on gas expenses in one year by buying a new car that goes 50 miles for each gallon of gas?

Saving = old cost - new cost

Saving = (\$4 * 1000/30 per month for a year) - (\$4 * 1000/50 per month for a year)

Saving = (4000/30 * 12) - (4000/50 * 12)

Saving = (1600) - (960)

Saving = \$640 a year
