Answer 1

Answer:

Step-by-step explanation:

The remaining oil which is to be added is given by :

1200 - 450 = 750 litres

Each liter costs :

81.5 p per liter.

The discount per liter is 7.5%.

The discount per liter is thus :

7.5/100 × 81.5 = 6.1125 p

This is per liter.

For 750 liters we have :

750 × 6.1125 = 4584.375 p

We convert p to £

1 p = 0.01£

4584.375 × 0.01 = £ 45.84375
