Answer:

£45.84

Step-by-step explanation:

First we will find out how much oil he will be buying. Because he wants to top it off, he will be filling the tank to it's capacity. So we will subtract the amount of oil already in the tank from the max capacity.

1200 - 450 = 750

Now we will find out how much that amount of oil will cost by multiplying it by the cost of oil per liter.

750 * 81.5 = 61125

We will convert the pence to pound sterling.

61125 / 100 = 611.25

He will get a 7.5 discount on the oil, so we will find 7.5% of that by multiplying it.

611.25 * .075 = 45.84375

Then we round the answer down to 45.84.
