How many acres are in a description reading, "The NW¼ of the SE¼ and the S½ of the SW¼ of the NE¼ of Section 4"?
The main answer is that the description "The NW¼ of the SE¼ and the S½ of the SW¼ of the NE¼ of Section 4" does not provide enough information to determine the exact number of acres.
The description only specifies the fractional parts of various quarters within Section 4, but it does not specify the size of the section or the size of each quarter.
To determine the number of acres, we need to know the total area of Section 4 in acres. A section of land typically consists of 640 acres, but the exact size can vary depending on the jurisdiction or survey system being used. Once we know the total area of Section 4, we can calculate the number of acres based on the given fractional parts.
For example, if Section 4 is 640 acres, the NW¼ of the SE¼ would be (1/4) * (1/4) * 640 = 40 acres. The S½ of the SW¼ of the NE¼ would be (1/2) * (1/4) * (1/4) * 640 = 20 acres. However, without the information on the size of Section 4, we cannot accurately determine the total number of acres based on the given description.
In summary, the provided description only specifies fractional parts of various quarters within Section 4, and without the total area of Section 4, it is not possible to determine the exact number of acres.

Calculate your anticipated profits, assuming you take a position in three contracts. (do not round intermediate calculations. Round your answer to the nearest whole number. ) c. What is the size of your profit (loss) if the futures price is indeed an unbiased predictor of the future spot price and this price materializes? (a negative value should be indicated with a minus sign. Do not round intermediate calculations. Round your answer to the nearest whole number. )
For a speculative position, it is good to attempt a long position to attempt to profit from your beliefs. The Anticipated profit is $1,917.
A. I would enter into a long position to attempt to profit from your beliefs.
B. To calculate anticipated profits, first we would calculate the profit per contract:
Profit per contract = (spot price - futures price) x contract size
Future price = 0.05182 per mxn
Spot rate = 0.05821 per mxn
Contract Size = 100,000(assume)
Profit per contract = (0.05821 - 0.05182) x 100,000
= $639
Then, for three contracts the anticipated profits are:
Anticipated profits = profit per contract x number of contracts
Given the number of contracts = 3
= $639 x 3
= $1,917
Therefore the Anticipated profit is $1,917.
C. The futures price is an unbiased predictor of the future spot price and if the spot price materializes, your profit or loss would be zero your long position would balance of profit or losses from the spot price. So your profit in this case would be $0.

Michelle's Fine Furniture desires to increase its warehouses from two to three in its market areas, and the manager wants to know the impact this will have on its system inventories. The current average inventory level is approximately 3,000 units at each of the two warehouses. Use the square root rule to calculate the new inventory level needed to maintain the same level of stockouts &. Using the information in Problem 7. if Michell's preferred instead to go with one centrally located warehouse, how would this impact system inventories?
To calculate the new inventory level needed to maintain the same level of stockouts when increasing the warehouses from two to three, we can use the square root rule. The square root rule states that inventory should increase proportionally to the square root of the increase in the number of warehouses.
In this case, the number of warehouses is increasing from two to three, which is a 50% increase. Therefore, the square root of 1.5 is approximately 1.225. To maintain the same level of stockouts, the new inventory level needed would be 1.225 times the current average inventory level.
Calculating this, the new inventory level needed at each warehouse would be approximately 3,000 units * 1.225 ≈ 3,675 units.
Now, if Michelle's Fine Furniture preferred to go with one centrally located warehouse instead of multiple warehouses, it would impact system inventories differently. Consolidating into a single warehouse generally allows for better coordination and control over inventory. It may lead to more efficient inventory management and potentially lower overall inventory levels. However, the specific impact on system inventories would depend on factors such as transportation costs, demand patterns, lead times, and other logistical considerations. It would be necessary to conduct a comprehensive analysis considering these factors to determine the exact impact on system inventories in such a scenario.
