RiоVistа A prоgrаm using Vistа and running оn a system with the Rio file cache is trying to atomically update the variables foo and bar within a transaction, where both are within the specified data range. The initial value of each is set to TRUE. Within the transaction, foo is set to FALSE and later bar is set to FALSE. For each question, explain your choice using 1-2 succinct bullets. a) [2 points] The system crashes due to a kernel panic just after setting the value of foo and before setting the value of bar. What will be the persisted values of foo and bar before its crash recovery is started?

Yоur firm sells twо gоods, X аnd Y. There аre three customers who hаve different valuations for your products, but you cannot determine which customer is which, and thus cannot charge a different price for each customer. Each customer wants to buy at most one unit of X and one unit of Y. Your firm’s cost of producing each good is zero. The valuations for each consumer are as follows: Customer Product X Product Y 1 $80 $10 2 $70 $160 3 $10 $180 a) If the firm can charge only a single price for each good, how much profit does it earn? Profit = [profit_a] b) Now assume that the firm sells only a bundle of one X and one Y. How much profit does it earn? Profit = [profit_b] c) Now assuming that the firm can sell X and Y as a bundle as well as individually. How much profit does it earn? (note: each customer buys AT MOST one unit of X and one unit of Y) Profit = [profit_c]
