How do you calculate the average daily balance for the month?

The average is determined by summing up the data sets accumulated and then divided by the number of data points. In this case, we sum up all of the balances  in a day in one month- that is for 30 days and divide the total by 30. This is the average daily balance. 

You need to include the original coordinates of the triangle to answer this. and how much does it translate (move left right up down)
