Answer 1

= 40% decrease.

Answer 2

40 %

Answer 3

The general formula for percent decrease is:
\[\%\Delta = \frac{|a - b|}{a} \times 100\] , where a = original amount and b = new amount.

In this case, a = 200, b = 120

And 40% decrease is correct.

Actually, that's the formula for percent increase or decrease

Yes.
