She earned a total of $810. Of those, $162 was earned babysitting, while the rest(x), was earned in other services.
The upper bar should have the earnings separated($162 and x).
The bottom bar should have the total earnings($810). So the third option is the correct one.
Finding x:
Total 810, which can be separated in earnings of 162 and x. So
162 + x = 810
x = 810 - 162
x = 648
