50% discount refers to half of the original price, and the discount is 50%. Therefore, the 50% discount price can be calculated according to the following formula:
After discount price=original price × discount
The original price refers to the actual price of the goods, and the discount is 50%. Convert 50% to decimal, i.e. 0.5. Therefore, the formula can be written as:
Discount price=original price × 0.5
For example, if the original price of a commodity is 100 yuan, the 50% discount price is:
Discount price=100 yuan × 0.5=50 yuan
Therefore, the 50% discount price of this commodity is 50 yuan.
