Answer: the correct option is D.
Explanation:
Kurt's truck uses 8 gallons of gas to travel 112 miles. This means that the number of miles that his truck travels with one gallon of gas would be 112/8 = 14 miles per gallon.
He has 4 gallons in the tank. The number of miles that the 4 gallons would cover is
4 × 14 = 56 miles
If he needs to drive 266 miles, the number of miles left would be
266 - 56 = 210 miles
The number of gallons of gas that would cover 210 miles is
210/14 = 15 gallons
