We have to calculate the present value PV of a annuity.
The payment is yearly and it is P=60,000.
The interest rate is 5% (r=0.05), compounded annually (m=1).
The number of periods is n=20 years.
Then, we can use the formula for the present value of a annuity:
![\begin{gathered} PV=P\cdot(1-(1)/((1+r)^n))/(r) \\ PV=60000\cdot(1-(1)/(1.05^(20)))/(0.05) \\ PV\approx60000\cdot(1-(1)/(2.653))/(0.05) \\ PV\approx60000\cdot(1-0.377)/(0.05) \\ PV\approx60000\cdot(0.623)/(0.05) \\ PV\approx60000\cdot12.462 \\ PV\approx747720 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/im9bmm30fie135nchkl2scbxmppu6qrzd7.png)
