To find the marked down price of the television after a 25 percent discount from the original price of $250, you need to subtract the discount amount from the original price.
The discount amount can be calculated as:
\[ 0.25 \times 250 \]
Thus, the marked down price can be expressed as:
\[ 250 - (0.25 \times 250) \]
So the correct expression to find the marked down price is:
\[ 250 \text{ dollars minus } (0.25) \times (250) \]
This means the correct choice is:
250 dollars minus (0.25) (250)
