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?

Answers

25/100 x 250
= $62.50 is 25% of $250

250 - 62.50
= $187.50
Therefore, the marked down price is $187.50

Answer:

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

Mikes home street address number has 5 digits . Two digits have values of 50,000 and 200 . The digits in the ones place is 3 . The value of each of the other digits is ten times the value of the digits on its right . What is mikes home street address number ?

Answers

Answer: Mikes home street address number = 52233

Step-by-step explanation:

We need to make a 5 digit number such that

Two digits have values of 50,000 and 200 .

The digits in the ones place is 3 .

Now number is like 50,000 +x + 200 + y + 3  (ten thousand >  thousand > Hundred > tens > ones )

Need values for :  thousands place and tens place

The value of each of the other digits is ten times the value of the digits on its right .

thousands place value (x)= 200 x 10 = 2000

tens place value (y)= 3 x 10 =30

Required number =  50,000 +2000 + 200 + 30+ 3  = 52,233

∴Mikes home street address number = 52233
