Answer and explanation
Correct answer
D. Double price = 100.0; double discount = 20.0; double finalPrice = price * discount;
Why
Option 'c' wrongly applies the discount as multiplication instead of subtraction. The discount should be calculated as a percentage of the price and subtracted from the original price.
