Answer:
$1,600
Step-by-step explanation:
the owner of the SUV will spend $3,200 per year on gas:
- 12,000 miles driven per year / 15 miles per gallon = 800 gallons x $4 per gallon = $3,200
the owner of the more efficient vehicle will only spend half of that amount = $1,600 per year on gas:
the owner of the more efficient vehicle will save $1,600 per year on gas
