i have some good news and some bad news. the bad news is: no member of you family has ever lived past age 60. the good news is: think of how much social security money you family has saved the rest of us! anyway you just "celebrated" your 40th birthday (complete with all those lovely black balloons that read, "over the hill"). since you are certain the grim reaper will visit you in 20 years, you decide to purchase an investment that will pay you $4800 each year until reach room temperature that is age 60

if this investment returns 8% yo you, how mucj you be silling to pay for it?
