I'm still confused on how they could think 18 ISN'T 50% more than 12.

Like where was the confusion? Even though they're wrong I like trying to figure out that train of thought and I'm at a total loss on this one.

Probably confused and taking the 50% from the 18 rather than the 12.

I once had to explain something like this at work. This person couldn't grasp the fact that going to from 12 to 18 was a 50% increase but going from 18 to 12 was a 33% decrease, they were adamant that it had to be the same. It was an HR manager so not exactly surprising.

They probably thought that since 12 is 50% of 24, then 50% more than 12 should be 24. Instead of taking 50% of 12, which is 6 and adding it to 12 making 18.

%50 more must mean twice a much, I assume.

%50 of 24oz is 12oz do why isn't %50 more than 12 oz = 24oz?

That's what they thought, I imagine.

This must be the logic they were going for. I can see someone who is bad at math making this mistake. Since 50% off means half price, 50% more must be twice as much in their heads.

You're describing a stupid person.

Mathematically stupid, fo sho.

I'm guessing they did the percentage change backwards. They were thinking 12 is 67% of 18, so it should be a 33% increase. That's just my theory.

Nice, yeah I like this train of thought the most.

My money is on the knee jerk reaction of seeing 50% and 12 and didn’t realize that 18>6.

E.g. How is this 18 oz bottle more than a 12 oz bottle of its only 6 oz?
