Answer: £80
Explanation:
First, we need to calculate the number of gallons used by Sally. This will be:
= 560 / 34.5
= 16.23 gallons
Since 1 gallon = 4.55 litres, we calculate the number of liters and this will be:
= 16.23 × 4.55
= 73.85 liters
Since Petrol cost £1.08 per litre, the cost of the petrol will be:
= £1.08 × 73.85
= ££79.758
= £80 approximately
