jeyben [28]

Since the photo booth charges a $500 fee for two hours at the party and an additional 50 dollars per hour, we have:

50x+500=C

Where x is the hours stayed and C is the total cost. Since Cindy doesn't want to spend more than 700 dollars, we have:

50x+500=700 \implies\\ 50x=200\implies\\ x=4

So she spent an additional 4 hours on the rental.
