First, the value of each share rose by 2. So we have +2.
Then it fell by 5. So we have
2 - 5 = -3
Each share has a net value of negative 3.
Dave owns 15 shares. So,
15 * (-3) = -45.
So, there is a net loss of $45.
Answer:
A) the firm should hire additional workers.
Explanation:
if the marginal production of the tenth worker is 5 units or output and the price of each unit is $4, the the workers total marginal product revenue (MPR) = 5 units x $4 per unit = $20
Since the cost of hiring that tenth worker is $15 (less than MPR), then the company should hire more additional workers until the MRP = labor cost
When an economist says that "Kevin's income elasticity of red wine is 6" he means that if Kevin's income increases by 10%, the quantity of red wine demanded by Kevin rises by 60%. So, red wine is income elastic. Since the income elasticity is greater than 1, red wine is a luxury good for Kevin.
Income elasticity measures the change in the quantity of goods demanded relative to a change in income.
If an increase in income results in a decrease in the quantity of goods demanded, then that good is an inferior or cheap good. The income elasticity of a cheap good is negative.
If the demand for a good rises with an increase in income, then that good is a normal good. The income elasticity of normal goods is greater than zero.
If an increase in income results in a greater increase in the quantity of goods demanded, then that good is a luxury good. The income elasticity of a luxury good is greater than 1.
