A vacuum had been marked down by 20% and solf for $250. What was the original price of the vacuum?

The original price was $312.50

Step-by-step explanation:

If the vacuum was marked down by 20%, that means it was sold for 80% of the full price. It was sold for $250, so 80% of the original price is $250.

Let's set up an equation.

80/100 of x = 250

0.8 • x = 250

Divide both sides by 0.8.

x = 312.50

The original price was $312.50

Hope this helps!

I think the answer is 250.00

Step-by-step explanation:

Let the original price = x

  Original Price     -     Markdown       =     Sales Price

       x                 -     (20%)x           =         $250

  Note: 20% may be 0.20 or 20/100 as needed by the problem.

       x                -    0.20x                =         $250

      0.80x = $250

           x =   $312.50

Check:

     Is      312.50  -  (0.20)312.50  = 250.00   ?

               (0.80)(312.50) = 250.00   ?

                    250.00 = 250.00   ?yes

Hope this help you! :)
