Angela weighs 15% less than she did one year ago. which of the statements below is true?

Angela's current weight is 85% of her weight one year ago.

Justification:

Losing 15% means: x - 15% of x = x - (15/100) x = 0.15x = 0.85x.

And 0.85x = (85/100) x which is what 85% of x means.

Then, it has been shown that subtracting 15% yields 85% of the original amount.

So, for Angela's case, that means that losing 15% of the weight leads her to weight 85% of what her original weight was.
