Please help with the forecast using week days data

#1
Hi everyone,

Can someone please help with the forecast in Excel? Based on past 7 days of data, is it possible to forecast next 19 days?

As you can see from the data, weekend sales are low for all three products so I do need to factor in the 'day of the week'.

Should I be using the multiple regression? Any other method in Excel?

Thank you in advance!!

There are only 6 days with data. Does ths mean, at first
one has to predict a value for the first Wednesday?

, is it possible to forecast next 19 days?
Just Copy&Paste, I suppose. You don't have additional
information other than from the first week, so AFICS
you have to predict that all Mondays will show 90/43/8.
The same with the other weekdays.

With kind regards
