Final answer:
The total number of cars produced in three years is 532,379 cars.
Step-by-step explanation:
To calculate the total number of cars produced in three years, we need to add up the number of cars produced in each year.
First, we add the number of cars produced in 2007, 2008, and 2009:
- Number of cars produced in 2007: 127,695
- Number of cars produced in 2008: 98,895
- Number of cars produced in 2009: 305,789
Now, we add these three numbers together:
Total number of cars produced in three years: 127,695 + 98,895 + 305,789 = 532,379 cars
