A check-processing center uses exponential smoothing to forecast the number of incoming checks each month. The number of checks received in June was 40 million, while the forecast was 42 million. A smoothing constant of 0.25 is used.

Part 2

a) Using exponential smoothing and given , the forecast for the month of July = 41.541.5 million checks received (round your response to one decimal place).

Part 3

b) If the check-processing center received 44 million checks in the month of July, then using exponential smoothing and given , the forecast for the month of August = 42.142.1 million checks received (round your response to one decimal place).

please explain how to solve for bart b)
