Response:
There will be an increase in equilibrium quantity, but the impact on equilibrium price remains uncertain.
Note:
Due to the scientists' discovery, demand for oranges will rise, as will the price.
Additionally, the introduction of new fertilizers will boost the supply of oranges, leading to a price decrease.
Taking both of these factors into account indicates that there will be a rise in equilibrium quantity, while the effect on equilibrium price cannot be determined.
Answer:
Part a:
Show the probability density function for the waiting times at Kroger, assuming they are exponentially distributed.
Solution:
Probability density function f(x) = (1/ )*e-x/ = (1/26)*e-x/26 (result)
Part b:
Calculate the probability that a customer waits between 15 and 30 seconds.
Solution:
0.2462
Part c:
Determine the probability that a customer must wait longer than 2 minutes.
Solution:
0.0099
Explanation:
All calculations are included.
45.7mL/s = 45.7(3600)mL/(3600)s
= 164520mL/3600s
= 164520mL/hr
= 0.16452kL/hr
a. Using FIFO, the Cost of Goods Sold (COGS) is $17,640, while the Ending Inventory equals $12,960.
b. Under LIFO, COGS totals $19,160, while the Ending Inventory is $11,440.
c. The Weighted Average COGS is $18,360, and the Weighted Ending Inventory is $12,240.
For Cortez Company, the inventory particulars include initial stock of 100 units from $60/unit amounting to $6,000, first batch purchase of 150 units at $68 each totaling $10,200, and a second batch of 200 units at $72 each totaling $14,400, culminating in a total of 450 units valued at $30,600.
Queries about how COGS and Ending Inventory figures manifest under various methods (FIFO, LIFO, and Weighted Average) can be addressed based on those computations.
Answer:
To maximize utility, the consumption of product Y should be increased while reducing the intake of product X.
Explanation:
The utility-maximizing principle asserts that a consumer optimizes utility when the marginal utility per dollar spent is equal for both products.
For Product X, the marginal utility per dollar is:

= 2 utils per dollar
For Product Y, the marginal utility per dollar is:

= 8 utils per dollar
According to this principle, the consumer should increase the consumption of product Y and decrease that of product X.
