Answer:
-39.3%
Explanation:
Calculation for the IRR of his retainer offer
First step is to find Opportunity Cost
Opportunity Cost= 8 hours × $250 per hour
Opportunity Cost = $2,000
Since we have known the monthly Opportunity Cost the second step will be to compute IRR
Present Value= $30,000
N = 12
PMT = -2,000
FV = 0
Now let compute the IRR
IRR= -3.276502% × 12
IRR= -39.3180% Approximately - 39.3%
Therefore the IRR of his retainer offer is closest to: - 39.3%
