he number of pages varies from book to book. Let P be a random variable for page length. Suppose the random variable P has an expected value of 227 and a variance of 221. The price of a book depends on the length. Let the random variable C denote the price of a book in dollars. If C = 4 + 0.1*P, what is the expected value of the price of a book?
