Answer:
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.
