How to Determine the Best Buy

When faced with multiple deals, you can determine the best value by comparing the price per unit.

Steps to Find the Best Deal:

• Find the price per unit by dividing the total price by the number of items.
• Compare the price per unit for each deal.
• Choose the option with the lower unit price, as it offers the best value.

Example 1: Comparing Tin Prices

• Deal A: 3 tins cost $\pounds 1.20$
• Deal B: 4 tins cost $\pounds 1.80$

Step 1: Find price per tin

$$\frac{1.20}{3} = 0.40 \text{per tin}$$

$$\frac{1.80}{4} = 0.45 \text{per tin}$$

Final Answer: Deal A is better because 40p per tin is cheaper than 45p per tin.
