United States home front during World War II.

Cost of goods sold is an expense charged against sales to work out a gross profit (see definition below). So, for example, we may have sold 100 units this year at $4 each, and these 100 units that we sold cost us $3 each originally.
profits equal total revenue less total expenses for example say that at a price of $ 10 you think you can sell 200 products and incur fixed expenses of $ 1000 and marginal expenses of $ 800 the total revenue at this price level is 200 multiplied by $ 10 or 2000 total expenses are $ 1800 and profit is $ 200
