Answer:

  $356.00

Step-by-step explanation:

If d represents the discounted price, and p is the original price, you have ...

  d = p - 20% × p = p(1 -20%) = 0.80p

Then the original price is ...

  p = d/0.80 . . . . . divide by the coefficient of p

  p = $284.80/0.80 = $356.00

The price before the discount was $356.00.
