You are presented with an investment opportunity that will give you the following stream of cash flows: nothing for the next 10 years; starting at the following year, an amount of $8,000 per year until year 16; and after that year, then an amount of $3,000 per year until year 30. If your required rate of return (APR) is 12% compounded annually, what is the future value at end of year 30 of these cash flows?
