Geoff has taken his car to a mechanic for repair. The mechanic diagnosed the problem and has offered Geoff two possible repairs as a solution: Repair A: The repair costs $750. There is an 80% chance that this repair will solve the problem and no additional work will be needed.  If the repair doesn’t work, an additional repair will cost $400. Repair B: The repair costs $300. There is a 40% chance that this repair will solve the problem and no additional work will be needed.  If the repair doesn’t work, an additional repair will cost $800.  Using Expected Value Theory, which repair should Geoff tell the mechanic to make?  Be sure to show your work.
