Ответ:
Pv=pmt [(1-(1+r)^(-n))÷r]
Solve for pmt (amount of annual withdrawal)
Pmt=pv÷ [(1-(1+r)^(-n))÷r]
Now solve for the first plan
Pmt=28,000÷((1−(1+0.058)^(−4)) ÷(0.058))=8,043.59
Yield
8,043.59×4=32,174.36Answer
Solve for the second plan
Pmt=28,000÷((1−(1+0.07083)^(−3))
÷(0.07083))=10,685.63
Yield
10,685.63×3=32,056.89
So the answer is d
