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 $43$ million. A smoothing constant of $015$ is used

a$)$ Using exponential smoothing and given $,$ the forecast for the month of July $=426$ million checks received $($round your response to one decimal place$).$

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 $=$ million checks received $($round your response to one decimal place$).$
