[57] [58] [60] A study published in 2020 has found that Chegg answers student questions even though the questions have clear cues to indicate that the student is trying to buy answers for a current assessed activity—the questions are neither identified nor flagged as violations of academic integrity anywhere in the process.

Price and total revenue have a negative relationship when demand is elastic (price elasticity > 1), which means that increases in price will lead to decreases in total revenue. Price changes will not affect total revenue when the demand is unit elastic (price elasticity = 1). Maximum total revenue is achieved where the elasticity of demand is 1.
To verify a margin (%): Cost as % of sales = 100% − Margin % "When considering multiple products with different revenues and costs, we can calculate overall margin (%) on either of two bases: Total revenue and total costs for all products, or the dollar-weighted average of the percentage margins of the different products." [1]
Following a matching principle of matching a portion of sales against variable costs, one can decompose sales as contribution plus variable costs, where contribution is "what's left after deducting variable costs". One can think of contribution as "the marginal contribution of a unit to the profit", or "contribution towards offsetting fixed costs".
Total revenue, the product price times the quantity of the product demanded, can be represented at an initial point by a rectangle with corners at the following four points on the demand graph: price (P 1), quantity demanded (Q 1), point A on the demand curve, and the origin (the intersection of the price axis and the quantity axis).
The method used for determining revenue of a long-term contract can be complex. Usually two methods are employed to calculate the percentage of completion: (i) by calculating the percentage of accumulated cost incurred to the total budgeted cost; (ii) by determining the percentage of deliverable completed as a percentage of total deliverable.
Gross margin is a calculation of revenue less the cost of goods sold, and is used to determine how well sales cover direct variable costs relating to the production of goods. Net income/sales, or profit margin , is calculated by investors to determine how efficiently a company turns revenues into profits.
