I’m working on a computer science exercise and need support to help me learn.

On the right hand side of your worksheet, create a 5 X 6 matrix (as your table array or database…this is your lookup table), with column and row headers as follows (or select your own column headers). Note: you can make up your own…use the sample as created in class…or…use the sample as displayed below. Make-up your own numbers / information / descriptives.

Parameters and Criterion – continued

When your data information is completed meaning the database (right side)…then copy your column headers from your database and paste the column headers on the left side of your Excel worksheet.

Begin by using the “Item / Description” column for data validation as your ‘drop down box’.

Create a VLOOKUP function for each of the remaining and corresponding line item columns. Meaning, when a selected item (from your data validation list) is highlighted and clicked on…the corresponding information (from the right side table) is retrieved and it should populate the table with the identical information (from your table array) into the left side table.

Beneath the table create a row header called “Sub Total” and add the Qty column and add the Ext Amt.

Beneath the sub-total create a row header called ‘Sales Tax’ and use 6.5% as your multiplier to calculate the sales tax based on the sub-total amount.

Beneath the sales tax create a row header called “Grand Total” and create a formula that sums the sub-total and the sales tax.

Beneath the Grand Total number, create a row header called “Payment” and enter an amount greater than or equal to the Grand Total Amount.

Beneath the Payment, create a row header called “Balance Due” and create a formula that subtracts the Payment from the Grand Total.
