    Answer: 8,800,000

    Step-by-step explanation:

    First year recorded number of cars on the roads = 80, 000,000

    Increase rate = 10%

    In the second year, the number of cars recorded = 10% of 80,000,000

    = 10/100 x 80,000,000

    = 8,000,000

    = 80,000,000 + 8,000,000

    = 88,000,000

    In the third year, the number of cars recorded = 10% of 88,000,000

    = 10/100 x 88,000,000

    = 8,800,000

    = 88,000,000 + 8,800,000

    = 96,800,000.

    The number of cars we had more in the third years compared to year two will be

    = 96,800,000 - 88,000,000

    = 8,800,000
