9. For each of the following products, select Sufficient if the information provided is sufficient to determine whether the unit price of the product is less than €3. Otherwise, select Insufficient.
Answer: Sufficient : A,D;Insufficient: B,C
Sufficient information is available for Products A and D to determine if their unit prices are less than €3.
The information provided allows us to conclude that the unit prices for Products A and D can be assessed for whether they are below €3. However, for Products B and C, the information is insufficient to make that determination.
A) Product A
The data for Product A includes specific subtotal amounts from recent purchases, enabling us to calculate the unit price. Since the number of units purchased is an integer, we can derive whether the unit price is less than €3 based on the subtotal provided.
B) Product B
For Product B, the information lacks sufficient detail to determine its unit price. Although a subtotal is provided, without knowing the number of units purchased specifically for this product, we cannot ascertain if the unit price is below €3.
C) Product C
Similar to Product B, the information regarding Product C does not provide enough detail to make a determination about its unit price. The subtotal does not allow for a calculation of the unit price without knowledge of the quantity purchased.
D) Product D
The details provided for Product D include specific subtotal amounts and integer quantities purchased. This information is adequate to assess whether the unit price is less than €3, enabling a direct evaluation of the product's pricing.
Conclusion
In summary, the information available is sufficient for Products A and D to determine if their unit prices are below €3, while it is insufficient for Products B and C. The ability to compute unit prices from provided subtotals and integer quantities makes A and D clearly evaluable, whereas the lack of complete information for B and C renders them indeterminate.
