Answer: Her income elasticity of demand for cottage cheese is <em><u>0.3333</u></em> making it a <em><u>normal and necessary</u></em> good.
The income elasticity of demand is given by :
![\mathbf{YED = \frac{percentage change in demand}{percentage change in income}}](https://tex.z-dn.net/?f=%5Cmathbf%7BYED%20%3D%20%5Cfrac%7Bpercentage%20change%20in%20demand%7D%7Bpercentage%20change%20in%20income%7D%7D)
The percentage change in income is given as 60%. We calculate the percentage change in quantity demanded as follows:
![\mathbf{percentage change in quantity demanded = \frac{Q_{1}-Q_{0}}{Q_{0}}}](https://tex.z-dn.net/?f=%5Cmathbf%7Bpercentage%20change%20in%20quantity%20demanded%20%3D%20%5Cfrac%7BQ_%7B1%7D-Q_%7B0%7D%7D%7BQ_%7B0%7D%7D%7D)
![\mathbf{percentage change in quantity demanded = \frac{12-10}{10}}](https://tex.z-dn.net/?f=%5Cmathbf%7Bpercentage%20change%20in%20quantity%20demanded%20%3D%20%5Cfrac%7B12-10%7D%7B10%7D%7D)
![\mathbf{percentage change in quantity demanded = 0.2}\\](https://tex.z-dn.net/?f=%5Cmathbf%7Bpercentage%20change%20in%20quantity%20demanded%20%3D%200.2%7D%5C%5C)
Substituting the value above in the income elasticity demand formula we get,
![\mathbf{YED = \frac{0.20}{0.60}}](https://tex.z-dn.net/?f=%5Cmathbf%7BYED%20%3D%20%5Cfrac%7B0.20%7D%7B0.60%7D%7D)
<u>YED = 0.33333</u>
Since the income elasticity is positive, and since Shawna buys more cottage cheese after an increase in income, we can classify this good as a normal good.
Since the income elasticity is between 0 and 1 we can also conclude that cottage cheese is also a essential good or a necessity.
Answer: Marginal revenue is equal to price times quantity
Explanation:
A perfectly competitive market is a market where there's a large number of both the producers and the consumers have full and symmetric information.
In a perfectly competitive market, the marginal revenue is the same as price and the marginal revenue curve is the same as the demand curve facing sellers.
It should be noted that the statement that the marginal revenue is equal to price times quantity is incorrect. The total revenue is equal to price times quantity.
