You are presented with an investment opportunity that will give you the following stream of cash flows: nothing for the next $\{$n$1\}$ years; starting at the following year, an amount of $$4,000$ per year until year $11$; and after that year, an amount of $$10,000$ per year until year $25.$ If your required rate of return $($APR$)$ is $8\%$ compounded annually, what is the present value today of these cash flows?

Round to the nearest $$0\mathrm{.}01$ but do not use the $ sign. Enter as a positive number. Do not use commas to separate thousands. For example if you obtain $$1,432\mathrm{.}728$ then enter $1432\mathrm{.}73$; if you obtain $$432$ then enter $432\mathrm{.}00$
