A movie theater rewards its loyal customers by offering them discounts on the ticket price. For the first 10 movies that a person watches in the movie theater, the ticket price is $50 per movie. For each subsequent set of 10 movies, the ticket price reduces by $5 per movie till the point where the ticket price equals $25 per movie. The person then gets a lifetime discount and can watch all subsequent movies at a ticket price of $25 per movie.
