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

c$)$ Exponential smoothing may not be an appropriate method to use for the check$-$processing center because:

A$.$ the check$-$processing center's forecast is very hard to make as its processing requirements should have a very high variability

B$.$ the check$-$processing center should observe a cyclical trend in its processing requirements.

C$.$ the check$-$processing center should observe an increasing trend in its processing requirements

D$.$ the check$-$processing center should observe seasonality in its processing requirements.
