Answer:
Machine C
Step-by-step explanation:
The expected monetary value (EMV) of machine A = $45,000 x 90% = $40,500
The expected monetary value (EMV) of machine B = $80,000 x 50% = $40,000
The expected monetary value (EMV) of machine C = $60,000 x 75% = $45,000
EMV of machine C is higher than the EMV of machines A and B
