Finance question???

Question

You can renew a subscription for $100 per year or $1000 lifetime, beginning immediately. Assuming you can earn 7% on your capital and the annual renewal rate will remain constant, how many years must you live to make the lifetime subscription the better buy? (Hint: Be sure you remember that you are solving for how many years you must live, not for how many payments must be made.)

Answer 1

It would take eight years for this to happen.
