Question

WILL MEDAL AND FAN!!! :D
Can anyone help me with a Geometry concept? Particularly on how to solve for percent decrease/increase? I'm struggling to apply the concept to a question I'm working on, an I'd appreciate it so so much if someone could explain it to me!!

Answer 1

@phi @ninjasandtigers @ilikemath50 @mathmate please help?

Answer 2

what exactly is giving you troubles?

Answer 3

Well, for the question I'm doing, it's asking for the percent change between the volumes of two tanks. Everything shows how to find percent increase, but not decrease. Is there a formula I'm supposed to use to find percent decrease?

Answer 4

the difference in an increase and a decrease is just the sign.
+ is an increase
- is a decrease

Answer 5

so, if something gets bigger it will increase by some %
if something gets smaller it will decrease by some %

Answer 6

Ok.... so I'm supposed to find the percent change between a tank with the volume 444012.76 and a model with a volume that I believe is 148004.25. Someone else tried to explain that they got 21,984...... percent change, but I don't get what they did...?

Answer 7

*21,984.44581

Answer 8

Wait, I made a mistake, sorry DX
The volume of the first tank is 443786. The model volume is 3 times smaller. How would I get the percent change between them?
If that's clearer.

Answer 9

I keep getting 33.33333408?
