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
