Answer:
B) in the short run, an unexpected change in the price of an important resource can change the cost to firms.
Explanation:
The short run aggregate supply (SRAS) curve is upward sloping because as the price of goods and services increases, the quantity supplied will increase. In the short run, wages are more sticky than prices, and businesses can adjust prices more rapidly than employees can get a raise. This will result in businesses increasing their profit margins as the general level of prices increases, therefore the SRAS curve will be upward sloping.
An unexpected change in the price of a key input will shift the entire SRAS curve either to the right (price of key input decreases) or to the left (price of key input increases).
Using formula: Marginal Utility=Change in Total Utility/Change in Quantity
<span>So, the marginal utility of each good will be 30/$2, or 15/$1.
Multiply this marginal utility by the price of each good/service to obtain the marginal utility per unit of good.</span>
<span>Since marginal utility of good A is given then by using this formula
the the marginal utility of good B is 60 , MU of good C is 45 and MU of good D is 15</span>
