Let's address each part of the problem:

### a) Which petrol is better value for money?

We need to calculate the price per litre for both Erin and Max.

- **Erin**: 
  \[
  \frac{£20.30}{14 \, \text{litres}} = £1.45 \, \text{per litre}
  \]

- **Max**: 
  \[
  \frac{£24.70}{19 \, \text{litres}} = £1.30 \, \text{per litre}
  \]

**Max's petrol** is cheaper at £1.30 per litre compared to Erin's petrol at £1.45 per litre.

### b) How much would 30 litres cost from the cheaper petrol station?

Since Max's petrol is cheaper, we will use his price to calculate the cost of 30 litres.

\[
30 \, \text{litres} \times £1.30 \, \text{per litre} = £39.00
\]

So, **30 litres of petrol** from Max's station would cost **£39.00**.

Would you like more details on this or have any questions? Here are some related questions:

1. How much would 30 litres cost at Erin's petrol station?
2. If Erin’s station reduced its price to £1.35 per litre, would it then be cheaper?
3. What would the price difference be if both bought 50 litres?
4. How much does each pay per litre if they bought an additional 5 litres at the same price?
5. How would the cost of petrol change if the price per litre increased by 10% at both stations?

**Tip**: Always compare prices on a per-unit basis to find the best value!

Erin and Max bought petrol from different petrol stations. Was Erin's petrol or Max's petrol better value for money? How much would 30 litres of petrol cost from the cheaper petrol station?

Find out which petrol is cheaper between Erin's and Max's. This problem involves comparing unit prices and calculating the cost for 30 litres at the cheaper station. Suitable for students in Grades 6-8.
