You waited to save and now you are $35$ and still expect to retire at age $65.$ How much would you have in your retirement account when you retire if you contribute $$10,000$ next year $($i$.$e$.,$ at t$=1$ when you are $36)$ and increase your annual contributions by $4\%$ every year after? Assume your account will earn $10\%$ annually. How much would the payment need to be to have the same amount as you would have had if you started right away $($when you were $30$ and made your first contribution at $31$ like in the problem right above$)?$
