She will have $103, you must multiply 8 by 10, then add 23 and you get 103.
So first we write out their respective charges
A=65+30x (x=hours of A)
B=30+47.5y (x= hours of B)
we want to know when A and B are equal so just set them to be equal
65+30x=30+47.5x
subtract 30 from both sides
35+30x=47.5x
multiplyboth sides by 2 to get rid of the nasty decimal
70+60x=95x
subtract 60x from both sides
70=35x
divide both sides by 35
2=x
they must work 2 hours for them to be equal
Answer:
The equation 
gives average time spent on 35 rehearsals.
Step-by-step explanation:
Please consider the complete question.
The play director spent 190 hours preparing for a play. That time included attending 35 rehearsals that took varying amounts of time and spending 
hours on other responsibilities related to the play. What question does the equation help answer?
Since time spent on each rehearsal is 35 hours, so time spent on 35 rehearsals would be 
.
hours is time spent on other responsibilities related to play. The sum of these times equals to total time spent on preparing the play.
Now let us solve our equation step by step.
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 gives average time spent on 35 rehearsals.
