Attendance at a cinema decreased by 12 %.
How many percent should the price of the movie ticket be raised so that the revenue would only decrease by 5 %?
Assume there are 100 at $1 each in attendance originally
A 12% decrease means only $88 in revenue
A 5% decrease mean $95 in revenue
95 - 88 = 7% increase in price to have 95% revenue
