The marginal cost for printing a paperback book at a small publishing company is C(p) = $0.015 per page where p is the number of pages in the book A 770 page book has a $19.85 production cost. Find the production cost function C(p). Suppose that in a memory experiment the rate of memorizing is given by M '(t) = 0.009152 + 0.915, where M '(t) is the memory rate, in words per minute. How many words are memorized in the first 11 minutes? Round your answer to the nearest whole word
