A company estimates that it can sell 5,000 headphone each week if it prices each set of headphones at $20. However, its weekly number of sales will increase by 1000 units for each $1 decrease in price. At what price is revenue maximum? What is the maximum revenue and how many sets of headphones should the company expect to sell? Write your conclusions in a sentence.

When the price is higher than $12 per unit, demand is elastic, which means any decrease in price will result in a larger proportional increase in quantity demanded. This in turn increases total revenue. Below $12 per unit, demand is inelastic, which means that a decrease in price will result in a smaller increase in quantity demanded.
