Given:

discount of 25%

Hasan's equation: d - 0.25d

Bella's equation: 0.75d

d represents the original price.

0.25d represents the discount.

0.75d represents the discounted price.

Example: 1,000 is the price. d = 1,000

0.25d = 0.25 (1000) = 250 this is the discount

0.75d = 0.75 (1000) = 750 this is the discounted price

Hassan: d - 0.25d = 1000 - 250 = 750

Bella: 0.75d = 0.75 (1000) = 750
