Solution
Since we want to know how much money is spent in June, July and August, we need the difference between the amount of money spent by the beginning of June and the amount of money spent by the end of August.
We estimate these to be about 
million and 
million, respectively. The difference is
![\[4.8-2.2=2.6\approx 2.5 \rightarrow \boxed{\text{B}}\]](http://latex.artofproblemsolving.com/7/7/b/77bd93d3dce520dcc09b4c6865536b38cea41f9d.png)
