Work out the total amount Mrs Smith paid for the oil she bought in March. 1
Oil Added to 1000 litres:
£750 ÷ 50p = 750 ÷ 0.5 = 1500 litres
So, a full tank contains = 2500 litres
Oil Needed to fill in March:
= 2500 – 600 = 1900
New oil cost per litre:
= 50p + 4%
10% = 5p
1% = 0.5p
4% = 2p
New price = 52p
1900 litres x 52p = 98800p
= £988
