A department store is running a promotion. As you enter the store, you are 4 points
given a scratch-off card with 25 spots from which to choose. At the
register, you will scratch off one spot and get that amount of money off
any purchase over $30. On the card, there are eight $1-off spots, five $5-
off spots, three $10-off spots, one $20-off spot and one $30-off spot. Use
the table below to help determine the expected value/fair price. Explain
the steps you took to get your answer.
