1. The effective cost price includes all expenses necessary to acquire and make the timber ready for use. 2. These expenses are the supplier invoice, transportation insurance, and specialized handling equipment costs. 3. Calculate the total cost: $100,000 (invoice) + $5,000 (insurance) + $3,000 (handling) = $108,000. 4. The total quantity of timber purchased is 200 cubic meters. 5. Calculate the effective cost price per cubic meter: Total cost / Quantity = $108,000 / 200 = $540. Why others are wrong: A — Correct option. B — Incorrectly calculates the cost price based only on the supplier invoice, excluding insurance and handling costs. C — Incorrectly calculates the cost price by including the handling equipment cost but excluding the transportation insurance cost. D — Incorrectly calculates the cost price by including the transportation insurance cost but excluding the specialized handling equipment cost.

Calculate the total expenditure incurred to make the watches ready for sale. Initial purchase cost: $5000 Customs and shipping cost: $1000 Refurbishment cost: $500 Total expenditure = $5000 + $1000 + $500 = $6500 Determine the number of watches actually available for sale. Initial number of watches: 100 Watches discarded: 20 Number of watches available for sale = 100 - 20 = 80 Calculate the effective cost price per watch. Effective Cost Price per watch = Total expenditure / Number of watches available for sale Effective Cost Price per watch = $6500 / 80 = $81.25 Why others are wrong: A — Correct. B — This is the initial purchase price per watch ($5000 / 100), ignoring all additional costs and discarded units. C — This calculates total expenditure ($6500) divided by the initial number of watches (100), incorrectly assuming all watches were made available for sale. D — This considers initial purchase and shipping costs ($5000 + $1000 = $6000) divided by the initial number of watches (100), ignoring refurbishment costs and discarded units.

Let CP be the Cost Price of the sculpture. Selling Price (SP) = $320. Loss = 20% of CP. When there's a loss, SP = CP - (Loss % of CP) = CP * (1 - Loss %). So, $320 = CP * (1 - 0.20) = CP * 0.80. To find the Cost Price (CP): CP = $320 / 0.80 = $400. Now, the craftsman wants to achieve a 15% profit on the Cost Price. Desired Profit = 15% of CP. New Selling Price = CP + (Profit % of CP) = CP * (1 + Profit %). New Selling Price = $400 * (1 + 0.15) = $400 * 1.15. New Selling Price = $460. Why others are wrong: A — This could result from calculating a 10% profit ($400 * 1.10 = $440), or by incorrectly calculating CP as $384 (by taking 20% loss on SP, then adding to SP) and then adding 15% profit. B — This is the correct answer. C — This could result from calculating a 20% profit instead of the desired 15% ($400 * 1.20 = $480). D — This could result from calculating a 25% profit instead of the desired 15% ($400 * 1.25 = $500).

1. The company is incurring a "significant capital expenditure" for new machinery. 2. This capital expenditure is "amortized evenly over the first year's projected system sales," meaning a portion of this large fixed cost is added to the cost of each system produced in the first year. 3. Additionally, "new specialized personnel" implies new labor costs, which also contribute to the cost price. 4. While the goal is "potential long-term cost efficiencies," the immediate effect of absorbing a new large investment and new labor costs into the cost per unit will generally lead to an initial increase in the calculated cost price. Why others are wrong: A — The direct material cost for the *entire system* is not guaranteed to decrease; only the raw materials for the brackets might change, and other system materials are unaffected. B — While some material costs for brackets might change, the addition of "new specialized personnel" introduces new labor costs, making a total variable cost decrease unlikely immediately. C — This is the correct answer. D — If the cost price increases, and assuming the selling price remains constant, profitability would likely decrease, not improve, in the immediate term.

Step 1: Identify the initial purchase price of each smartphone, which is 500 monetary units. Step 2: Identify additional direct costs incurred *per phone* to make it ready for sale or enhance its value/appeal. These are 20 monetary units for the extended warranty and 10 monetary units for promotional display materials. Step 3: Sum all these relevant costs to determine the total effective cost price per unit. Step 4: Calculate: 500 + 20 + 10 = 530 monetary units. Why others are wrong: A — This option only considers the initial purchase price, omitting additional direct costs associated with making the product ready for sale. B — This option incorrectly omits the cost of the extended warranty package. C — This option incorrectly omits the cost of the promotional display materials.
