B. (1.0-0.25)p
C.0.75p
D.0.25p

Answer 1

D, because the answer would be 0.75p and all the rest make 0.75p and D does not 

Answer 2

Answer: D. 0.25p

Step-by-step explanation:

The original price of an item = p dollars

After 25% discount the price of that item =$p-25\%\ of\ p$

Let's solve the above expression

$p-25\%\ of\ p\\=p-\frac{25}{100}\timesp$

Taking p as common outside of the expression, we get

$p(1-\frac{25}{100})\\=p(1-0.25)\\=p(0.75)$

The only expression which is not equivalent to the price of the item with the discount = 0.25 p
