Two brands of shampoo are for sale in the shop. Brand A is 350ml for €5.29 and Brand B is 700ml for €8.99. Which brand is better value?

1. Break Down the Problem

To determine which brand of shampoo offers better value, we'll calculate the price per milliliter for both Brand A and Brand B.

2. Relevant Concepts

The price per milliliter can be calculated by dividing the total price by the total volume of the product. The formula is: $\text{Price per ml} = \frac{\text{Total Price}}{\text{Total Volume (ml)}}$

3. Analysis and Detail

For Brand A:

• Total Price = €5.29
• Total Volume = 350 ml $\text{Price per ml for Brand A} = \frac{5.29}{350} \approx 0.0151 \, \text{€ per ml}$

For Brand B:

• Total Price = €8.99
• Total Volume = 700 ml $\text{Price per ml for Brand B} = \frac{8.99}{700} \approx 0.0128 \, \text{€ per ml}$

4. Verify and Summarize

Now, we have calculated the price per milliliter for both brands:

• Brand A: €0.0151 per ml
• Brand B: €0.0128 per ml

Brand B has a lower price per milliliter, indicating that it provides better value for money.

Final Answer

Brand B is the better value option at approximately €0.0128 per ml.
