Hello. I am struggling to understand how annuities are used in a healthcare setting. I understand how to do the calculations in excel but am struggling to understand how annuities are used in the healthcare industry and what PV and FV has to do with it.

Solve your own original TVM problems: (1) present value of an annuity, and (2) future value of an annuity. Your scenarios may be fictitious, but they should make sense in the real-life context of your industry.

Please note I am only needing help with explaining how annuities can be used in a healthcare setting, and not looking for equation help. I am not understanding how this applies, but am being asked to do so, please clarify. Thank you.
