The answer is A which is 113. Hope this helped

In order to find out out how many bicycles were rented per day in September,, you must remove %10 (.10) from 126.
start value:           percentage of your start value:                end value:
126                  -                      %10                                           113.4
this means that in September,, an average of 113.4 bicycles were rented per day,, but we dont stop there. in order to get an average number that matches the option choices,, we must either round up or down. if the first number behind the decimal is less than 5,, round down but if it is 5 or larger,, round down. when looking at the first number behind the decimal you will see that it is smaller than 5,, so we round down to 113. this means that the correct answer to your question will be option A,, 113.
