Question

Mr Leonard wants to top-up his central heating oil tank.

Answer 1

First let us calculate the Liters of oil that we need to top-up:

Volume oil needed = 1200 L – 450 L = 750 L

 

Then calculate the total price of 750 L of oil:

Total price = 81.5p / L * 750 L = 61,125p

 

The discount percent is 7.5% or 0.075 in decimal, therefore the total discount is:

Total discount = 61,125p * 0.075

Total discount = 4,584.375p

Answer 2

Answer:

The discount is 4584.375 p.

Step-by-step explanation:

Given :  The oil tank can take up to 1200 litre of oil. There are already 450 litres of oil in the tank.

The price of oil is 81.5p per litre . As a loyal customer, Mr Leonard gets a 7.5% discount on the price of the oil.

To find : How much discount does Mr Leonard get on this purchase?

Solution :

First we find out the number of litre required in the tank

Total capacity of tank = 1200 litre of oil

There are already 450 litres of oil in the tank.

The required oil is = 1200 L – 450 L = 750 L

The price of oil is 81.5 p per litre.

i.e, 1 liter oil price is = 81.5 p

For 750 liter oil price is = $81.5\times 750=61125p$

There is 7.5% discount on the price of oil.

i.e, $61125\times\frac{7.5}{100}=4584.375$

The discount is 4584.375 p.
