Suppose you will receive $17,000 in 6 months and another $13,000 in 18 months. If the discount rate is 6% per annum (compounding monthly) for the first 9 months, and 14% per annum (compounding monthly) for the next 9 months, what single amount received today would be equal to the two proposed payments? (answer to the nearest whole dollar; dont include the $ sign or commas).
