Answer:
The present value of a perpetuity is calculated as follows:
= Cashflow / Discount rate
a. Present value of $400 perpetuity discounted at 15%
= 400 / 0.15
= $2,666.67
b. Present value of $3,000 perpetuity discounted at 19%
= 3,000 / 0.19
= $15,789.47
c. Present value of $110 perpetuity discounted at 16%
= 110 / 16%
= $687.50
d. Present value of $60 perpetuity discounted at 12%
= 60 / 0.12
= $500
