Answer:
1.91 years
Explanation:
The car manufacturer assumed that the owners of both cars would drive them on average 16,500 miles per year. So they made all their cost calculations based on that average annual mileage, and the final result was the crossover point of 31,449 miles. To determine the crossover point in years, all you need to do is divide 31,449 miles by 16,500 miles = 1.906 years ≈ 1.91 years
