Purchases You are about to place book orders from McPhearson Imprints and O’Conell Books (see Exercise 32) when you get an e-mail from McPhearson Imprints saying sorry, but they have stopped publishing romance novels because of the global romance crisis and can now offer only packages of 10 horror novels for $50. O’Conell is still offering packages of 10 horror novels and 10 romance novels for $90, and now the U.S. Treasury, in an attempt to bolster the floundering romance industry, is offering its own package of 20 romance novels for $120. Furthermore, Congress, in approving this measure, has passed legislation dictating that at least two thirds of the packages in every order must come from the U.S. Treasury. As before, you wish to obtain at least 5,000 horror novels and 4,000 romance novels at minimum cost. Taking all of this into account, how many packages should you purchase from each supplier? What is the minimum cost?
