You have just turned $22$ years$$ old, received your$$ bachelor's degree, and accepted your first job. Now you must decide how much money to put into your retirement plan. The plan works as$$ follows: Every dollar in the plan earns $7\mathrm{.}5\%$ per year. You cannot make withdrawals until you retire on your $65$th birthday. After$$ that, you can make withdrawals as you see fit. You decide that you will plan to live to $100$ and work until you turn $65.$ You estimate that to live comfortably in$$ retirement, you will need $$90,000$ per$$ year, starting at the end of the first year of retirement and ending on your $100$th birthday. You will contribute the same amount to the plan at the end of every year that you work. How much do you need to contribute each year to fund your$$ retirement?
