A lottery has a grand prize of $120,000, two runner-up prizes of $15,000 each, four third-place prizes of $6000 each, and eight consolation prizes of $1200 each. If 480,000 tickets are sold for $1 each and the probability of any one ticket winning is the same as that of any other ticket winning, find the expected net winnings on a $1 ticket. (Round your answer to two decimal places.)

= -0.62
