Answer:
The equation 
gives average time spent on 35 rehearsals.
Step-by-step explanation:
We have been given an equation and we are supposed to find that the given equation helps to find answer of what question.
We can see that 
is time spent on other responsibilities related to play and 35x represents time spent on 35 rehearsals. The sum of these times equals to total time spent on preparing the play.
Now let us solve our equation step by step.
After subtracting 
hours from 190 hours we will get time spent on 35 rehearsals.
Time spent on 35 rehearsals is 96.25 hours and we are told that each rehearsal took different amount of time. Dividing 96.25 by 35 we will get average time spent on each rehearsal.
Therefore, equation finds average time spent on 35 rehearsals.
