When you buy a set of speakers, Best Buy asks if you would like to purchase insurance for your speakers. Assume that paying for new speakers for customers who listen to music at a reasonable level (thus minimizing damage) costs, on average, $150, and paying for new speakers for customers who listen to music very loudly (more likely to damage the speakers) costs, on average, $1000. Individuals know whether they like music at a reasonable level or at a loud level, but Best Buy can assume that 40% of listeners are reasonable listeners, and 60% are loud listeners. How much does Best Buy have to charge in order to break even?

a.) $660

b.)$150

c.) $1000

d.) $575
