Assume that you are $26$ years old today and that you are planning on retirement at age $68.$ Your current salary is $$40,000$ and you expect your salary to increase at a rate of $6\%$ per year as long as you work. To save for your retirement, you plan on making annual contributions to a retirement account. Your first contribution will be made on your $27$th birthday and will be $10\%$ of this year's salary. Likewise, you expect to deposit $10\%$ of your salary each year until you reach the age of $68.$ Assume that the rate of interest is $8\%.$ How much money will you have in your retirement account at age $68?$
