Textbook Question
Chapter 6.5, Problem 50E
Work these exercises. (See Example 4.)
Bulk Shipments Boxed.com is a company that shipsgrocery items in bulk. As the purchasing manager for a start-up, you decide to compare Boxed.com prices with your currentsupplier for an order of Charmin toilet paper (30 count ultrasoft) and Bounty paper towels (12 count double rolls). Matrix A shows the quantities that the production and sales departments need to order, and matrix B shows the prices foreach supplier. (Data from: www.boxed.com.)
a. Find the matrix product AB.
b. What do the rows of AB represent?
c. What do the columns of AB represent?
d. What would the total cost be (for both departments) if you order from Boxed.com? From your current supplier?
