For each of 18 recent purchases that included each of Products A - D, the table shows the product subtotals (the unit price for that product multiplied by the number of units bought as part of that purchase). For example, the table shows that, in the purchase corresponding to Receipt 1, €14.0 of the total purchase was due to the purchase of units of Product D. For each product, the number of units bought was always an integer and the unit price was the same for each of the 18 purchases.

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 Ã¢â€š¬3. Otherwise, select Insufficient.

Rationale

Sufficient information is provided for Products A and D.

For both Product A and Product D, the subtotals in the table can be divided by an integer number of units purchased to determine the unit price. If the subtotal is less than €3 multiplied by the number of units, we can conclude that the unit price is indeed less than €3.

A (Product A) YOUR ANSWER

The information for Product A allows us to calculate the unit price by using the subtotal and the integer number of units purchased. If the subtotal is less than €3 multiplied by the number of units, we can confirm that the unit price is less than €3, making the information sufficient.

B (Product B) YOUR ANSWER

For Product B, while we have a subtotal, we do not have enough information about the number of units purchased relative to the subtotal to definitively ascertain whether the unit price is less than €3. Therefore, the information is insufficient.

C (Product C) CORRECT

Similar to Product B, the information for Product C does not provide enough clarity regarding the relationship between the subtotal and the number of units bought. Without this, we cannot determine if the unit price is less than €3, leading to insufficient information.

D (Product D) YOUR ANSWER

The information for Product D is sufficient because the subtotal can be divided by the integer number of units purchased to determine the unit price. If the resulting unit price is less than €3, we have the necessary conclusion, thus making the information sufficient.

Conclusion

The determination of whether the unit price is less than €3 can be definitively made for Products A and D given the provided subtotals and integer units. In contrast, Products B and C lack sufficient information to arrive at a conclusion regarding their unit prices, highlighting the importance of the relationship between subtotal and quantity in making price assessments.

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 Ã¢â€š¬3. Otherwise, select Insufficient.

Sufficient information is provided for Products A and D.
