101.76 kg

======================

Let's denote Karen's original weight as x. Given that she lost 15% of her original weight, we have:

  • 0.85 x = 86.5

To solve for x, we divide both sides of the equation by 0.85:

  • x = 86.5  / 0.85
  • x ≈ 101.76 kg

Karen's original weight was approximately 101.76 kg.
