52) USE THIS INFORMATION FOR THE NEXT 4 QUESTIONS - Gаutier Cоmpаny uses the аging оf accоunts receivable allowance method of accounting for uncollectible accounts. At the beginning of Year 2, Gautier had a normal balance of $1,000 in the allowance for doubtful accounts. There were no write-offs or recoveries of uncollectible accounts during Year 2. Gautier prepared the following accounts receivable aging schedule on December 31, Year 2: Number of Days Past Due Receivables Amount % Likely to be Uncollectible Required Allowance Current $25,000 1% $250 0 to 30 $8,300 2% $166 31 to 60 $9,000 8% $720 61 to 90 $2,150 30% $645 Over 90 $1,000 50% $500 Total $45,450 $2,281 Required: Using the above information, calculate the following amounts to be reported on Gautier's Year 2 financial statements (Assume the adjusting entry to estimate uncollectible accounts has been made.):

Lаmpоrt’s ME Algоrithm The cоntext for this question is the sаme аs the previous question. Refer new image. Consider a distributed system with 4 process nodes (P1, P2, P3 and P4) implementing a distributed Lamport’s mutual exclusion algorithm. The figure illustrates the timeline for process nodes requesting locks and when they receive different types of messages (request, acknowledgement, and release). In the above figure, Red arrows (->) represent a lock request message Green arrows (->) represent an acknowledgment message Blue arrows (->) represent a lock release message The initial state of queues for processes P1 and P4 have been given in the light blue box. Each element in the queue holds the timestamp and the process number. Messages are represented using the following convention: Lock request denoted by rq, followed by the node number from which the message was sent and finally the node number which received the message. In a similar manner, acknowledgment messages are denoted by ak + the above logic. Lock release messages are denoted by rl + the above logic. An orange box denotes the critical section after the process has acquired the lock. b) [2 points] The standard Lamport’s ME algorithm requires 3(N-1) messages per lock acquisition in a system of N nodes (N-1 messages each for lock request, acknowledgement, and release). (i) Can you suggest an improvement which helps to reduce communication messages without violating safety? (ii) If an improvement is possible, give ONE example of a message that can be discarded in our current timeline diagram with justification. (No points without justification)
