Question

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

Answer 1

The current weight $W_c$ is 15% less than the weight Angela had 1 year ago ($W$). Or we can write,

$W_c=(1-\frac{15}{100}) W\\ W_c=\frac{85}{100}W$.

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

Answer 2

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