• A car driver fills his car with 38 litres of petrol, which costs 98p per litre. He then uses 8 litres of petrol on his next journey. What is the total value of petrol left in his car after?
• He fills the car with 38 litres. He uses 8 litres from his last journey and it costs 98p per litre, so you need to work out…
• 38 x £0.98
.. 30 8 90 2700 720 2700 720 240 64
£37.24 8 240 64
The answer is £37.24 but we still have to take away the cost of 8 litres, so…
£37.24 - £7.84 = £29.40
