When calcuating the price (p) of an item that has been marked down by 25%, Denise states that the expression "p - 0.25p" will calculate the sale price. Kristal says that a shorter way to calculate the sale price would be to use the expression "0.75p." Who is correct?
Both Denise and Kristal are correct.
Denise's expression "p - 0.25p" can be simplified to "0.75p," which means the sale price is 75% of the original price.
Kristal's expression "0.75p" directly represents the sale price as 75% of the original price.
Therefore, both expressions are equivalent and will result in the correct sale price.
