Question

Please help me work this out:

Mr Leonard wants to top-up his central heating tank.
the oil tank can take up to 1200 liters of oil.
there already 450 liters of oil in the tank.

the price of oil is 81.5p per liter
as a loyal customer, Mr Leonard gets a 7.5% discount.

how much discount does he get on this purchase
give answer in £

Answer 1

4582

Explanation:

1200 - 450 = 750 (liters to buy)

(81,5* (7,5/100) ) = 6,11 ( discount per liter loyal customer )

750*6,11 = 4582

Answer 2

£45.84375

Explanation:

1200 - 450 = 750 litres

7.5% discount

7.5/100 × 81.5(750) = 4584.375 p

£45.84375
