• Suppose Alice and Bob are going to communicate using AES in CBC mode. Unfortunately Alice's message length (in bytes) is not a multiple of 16. Suppose the last block of her message is just a single zero byte. How can she pad out the last block so that she can use CBC mode? Since this needs to be a reversible operation, how does Bob recognize the padding and remove it?

Cane Company manufactures two products called Alpha and Beta that sell for $130 and $90, respectively. Each product uses only one type of raw material that costs $5 per pound. The company has the capacity to annually produce 102,000 units of each product. Its average cost per unit for each product at this level of activity are given below: Direct materials Alpha $ 25 Beta $ 10 Direct labor 22 21 Variable manufacturing overhead 17 7 Traceable fixed manufacturing overhead 18 20 Variable selling expenses 14 10 Common fixed expenses 17 12 Total cost per unit $ 113 $ 80 The company considers its traceable fixed manufacturing overhead to be avoidable, whereas its common fixed expenses are unavoidable and have been allocated to products based on sales dollars. Foundational 11-7 (Algo) 7. Assume that Cane normally produces and sells 42,000 Betas per year. What is the financial advantage (disadvantage) of discontinuing the Beta product line?
