Answer 1

Answer: 45.84375 pounds

Step-by-step explanation:

The total quantity of oil which mr leonard purchase = 1200 - 450 = 750 liters,

Since, the price of oil is 81.5 penny per liter,

Thus, the total amount he spent in the oil he purchased = 81.5 × 750 = 61,125 penny

Also, 1 penny = 0.01 pounds

Thus, the total price of oil = 61,125×0.01 = 611.25 pounds

According to the question,

He got 7.5% discount on the price of the oil,

Therefore, the total discount he got = 7.5 % of 611.25 = 0.075× 611.25 = 45.84375 pounds

Answer 2

Answer:

£45.84

Step-by-step explanation:

1200 - 450= 750 litres.

81.5 p per litres

= 81.5 x 750 = 61,125p  

1p = £0.01

61,125 x 0.01 = £611.25

7.5 % of 611.25= 0.075 x 611.25 = £45.84375 or £45.84
