Answer: 8.8 million


Step-by-step explanation:

Given: The number of cars in year 1= 80 million

As she  found that the number of cars on the roads increases by 10% each year.

Now, 10% of 80 million=[tex]0.10\times80\ million=8\ million[/tex]

Thus, the number of cars in year 2= 80 million+8 million=88 million

Now, 10% of 88 million=[tex]0.10\times88\ million=8.8\ million[/tex]

Thus, the number of cars in year 3= 88 million+8.8 million=96.8 million

Now, the difference in the cars in  year 3 compared to year 2=96.8 million-88 million

Thus, the difference in the cars in  year 3 compared to year 2=8.8 million
