Walmart is having a huge 25 % off sale!!!
IRISSAK [1]

9514 1404 393

Answer:

  $400

Step-by-step explanation:

If the price after taking 25% off is $300, then $300 is 75% of the original price.

  $300 = 0.75p

  $300/0.75 = p = $400

The original price was $400.

_____

<em>Check</em>

0.25 × $400 = $100

$400 -100 = $300 . . . . the price after taking 25% off
