Sara is on the beach and notices a marble game. It costs $1 to play. If a blue marble is pulled, she will win $10 (because there is only 1 in the bag). There are 5 red marbles, and pulling one of these results in a $5 win. All other colors result in a loss. There are 200 total marbles in the bag. What is the expected value if Sara plays this game? Round to the nearest cent. Do not round until the final calculation.
