The formula to calculate the amount after a 75% discount is:
\[ A = P - (P \times D) \]
Where:
A 75% discount means the price of an item or service is reduced by 75% of its original price. For example, if an item originally costs $100, a 75% discount would reduce the price to $25.
Assume the original price is $100:
Calculate the amount after 75% discount:
\[ A = 100 - (100 \times 0.75) = 100 - 75 = 25 \]
Therefore, the amount after a 75% discount is $25.
