Excel worksheet for marketing | Marketing homework help

Looking for someone to complete an excel worksheet which consists of 3 activities.

I know there is chapter 7, 8, and 9 on the Excel.

But ONLY do CHAPTER 8

8.1, 8.2, and 8.3

All work must be shown within the cell. Not just answers

For example : 2×2 = 4 and stuff like that

 

Below the excel is attached along with the book work with the question to make it easier.

 

All for 25$ due in 4 hours
