Calculate payback period (PP) of the following investment (market rate is 10% pa. under annual compounding): Time in years from Cash flows (CF) NOW 0 - 12,000 1 4,000 5,000 2 3 3 6,000 4 7,000 Important technical requirement: (1) Round up your final result to the 4 decimal places, e.g. 2.321233232 =approx. = 2.3212. Otherwise, Moodle will automatically treat your result as incorrect. (2) Non-final calculations - if several catculation steps were made - should be rounded to at least to 2 decimals when dealing with CFs calculations, to 4 decimals when dealing with MD/CON and to at least 6 decimals when dealing with interest rates (e.g. 1.6782% = 0.001678)
