I'm not good at math at all

Extrinix:

Okay well, if the value is decreasing, you'll need to flip the percentage value. 100% is max, so 100%-8% is 92%, which, when multiplied by the cars value, is what the next year's value is.

KikiTheElf:

oh

KikiTheElf:

I understand now

Extrinix:

Got it?

KikiTheElf:

yup
