A supermarket sells only two types of coffee products, coffee and cream. The store expects to sell $200 worth of coffee and $50 worth of cream each day. The inventory manager is looking at the standard deviation of daily coffee sales, which is $4, and the standard deviation of cream sales, which is $6 dollars. Suppose the correlation coefficient between coffee and cream is 0.9375. They expect to sell a total of $250 worth of coffee products (coffee and cream combined). What is the standard deviation of this supermarket's daily sale on coffee products (coffee and cream combined)? Show all your work.
