To calculate the discount that Mr. Leonard receives, we can follow these steps:
1. Calculate the total cost of filling the tank without a discount:
The tank can hold up to 1200 liters, and there are already 450 liters in the tank. So, the amount of oil needed to fill the tank is 1200 - 450 = 750 liters.
The price of oil per liter is 81.5p, which is equivalent to £0.815.
Therefore, the total cost without a discount is 750 * £0.815.
2. Calculate the amount of discount:
Mr. Leonard receives a 7.5% discount. To calculate the discount, we multiply the total cost without a discount by 7.5% (or 0.075).
3. Convert the discount to pounds:
To convert the discount from pence to pounds, we divide the calculated discount by 100.
4. Calculate the final discount amount:
Multiply the discount in pounds by -1 to represent a reduction in cost.
By following these steps, we can determine the discount amount that Mr. Leonard receives in pounds.
