Invoice-Total is computed on each line-item. All line-item totals are then added to get invoice total. A line-item is extended by multiplying quantity by unit cost. The product is the line-item total.'

Discount is computed as follows:

If Invoice-Total is $3,000 or over, discount is 20 percent.
If Invoice-Total is between $2,000 and $2,999, discount is 10 percent.
If Invoice-Total is between $1,000 and $1,999, discount is 5 percent.
If Invoice-Total is under $1,000, no discount allowed.
