Probability Question

#1
An ice cream company makes ice cream bars on sticks which sell for 10 cents. Suppose that the company puts a star on every 50th stick; anyone who buys a bar with a starred stick gets a free ice cream bar. If you decide to buy ice cream bars until you get a free one, how much would you expect to spend before getting a free bar?
