Strike the evil commie parts and I have heard this word for word.
“If you’re talking about 50% of the original value in both cases, yes, but not when you’re talking about a decrease followed by an increase”
And I’ve solidly lost them.
Percentages are multiplicative, not addative, so if you go down 50 and then up 50 (or vice versa) you end up at 75% of the original value.
Equation would be original value * (1 + % ÷ 100)
So if we start with 1, 1 * (1-50/100) = .5 .5 * (1+50/100) =.75
In simplified fractions, 1 * 1/2 * 3/2= 3/4
I know. Far too many people I’ve had exactly this conversation with don’t seem to be able to grasp that, though, no matter how I present it to them.
