Mr Watkins needs to buy oil for his central heating.

Mr Watkins can put up to 1500 liters of oil in his tank.

There are already 850 litres of oil in the tank.

Mr Watkins is going to fill the tank with oil.

The price of oil is 67.2p per litre.

Mr Watkins gets 5% off the price of oil.

How much does Mr Watkins pay for the oil he needs to buy?

Please help me with this problem, I keep getting different answers.

Best Answer

He needs to buy 1500 - 850 litres = 650 litres

Cost = 650litres * 67.2p/litre *0.95 = 41496p = £41.50 to the nearest p (assuming the p represents pence Sterling)

The 0.95 is because he pays 95% of the basic price (i.e. 5% off)
