Cоnsider tаble Wоrker(nаme,pаy) where name is a key, and the fоllowing two concurrent transactions. T1: Begin Transaction S1: update Worker set pay = 2*pay where name = 'Amy' S2: update Worker set pay = 3*pay where name = 'Amy' Commit T2: Begin Transaction S3: update Worker set pay = pay-20 where name = 'Amy' S4: update Worker set pay = pay-10 where name = 'Amy' Commit Assume that the individual statements S1, S2, S3, and S4 always execute atomically. Let Amy's pay be 50 before either transaction begins execution. Suppose both transactions T1 and T2 execute to completion with isolation level Read-Committed. What are the possible values for Amy's final pay?
