The best prediction for the number of regular spectators that the program will have in 6 years is obtained with the following formula: Pf = Po×(1-b) ^ t Where: Pf = final population Po = initial population b = decrease rate t = timpo in years So: Pf = 223.00×(1-0.047) ^ 6 Pf = 167,056 The answer is the last option.
