A store is marking down the price of a television 25 percent from the original price of $250. Which expression can be used to find the marked down price?

250 × 0.25

Step-by-step explanation:

x/250 × 25/100

cross multiply

100x = 250 × 25

100x = 6250

divide by 100

x = 62.5

62.5 is how much the price got marked down

original price - marked down amount = new discounted price

250 - 62.5 = 187.5

$187.50 is now the actual price

As for which expression can be used to find the marked down price, none are listed in this problem and I'm assuming its a multiple choice question considering the wording of "which"

how i solved it is through cross multiplication but another way is by using the expression:

250 × 0.25

this is because 25% equals 0.25

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
