Create the following formulas to assign the value in the invoice amount column to one of five columns—current, 1–30 days, 31–60 days, 61–90 days, and over 90 days: a. in current (column h), if the days past due equals 0, display the invoice amount (column f); otherwise, display a blank cell. b. in 1–30 days (column i), if the days past due is greater than or equal to 1 and less than or equal to 30, display the invoice amount (column f); otherwise, display a blank cell. c. in 31–60 days (column j), if the number of days past due is greater than or equal to 31 and less than or equal to 60, display the invoice amount (column f); otherwise, display a blank cell. d. in 61–90 days (column k), if the number of days past due is greater than or equal to 61 and less than or equal to 90, display the invoice amount (column f); otherwise, display a blank cell. e. in over 90 days (column l), if the number of days past due is greater than or equal to 91 days, display the invoice amount (column f); otherwise, display a blank cell.
