Answer:
≈ £ 4584.38
Step-by-step explanation:
Firstly, we need to find the number of litres that Mr. Leonard needs to fill up his tank:
We know that there is already 450 litres in the 1200 litre tank, so he must need 1200 - 450 = 750 litres.
I'm not quite sure what the variable p means, but I'm going to assume that p represents the number of litres and that 81.5 is the price per litre in pounds.
So:
Total price = 81.5p
Total price = 81.5(750)
Total price = £61125
We have to remember though that the question is asking for the <em>discount</em> and not the <em>discounted price</em>, so:
61125 × 7.5%
61125 × 0.075 = 4584.375
≈ £ 4584.38
0.2 if you mean 2/10 or 2.5 if you mean 10/2
