Okay im not sure what this term means..
Assuming original cost = 10
Reduced Cost = 2
Amt reduced = 8
Percentage reduction is (Old amount - New amount) ÷ Old Amount x 100%
In your example, the new amount is 2 and the old amount is 10, so the percentage reduction would be (10 - 2) ÷ 10 x 100% = 80%.
Why did the vector cross the road?
It wanted to be normal.
that was lightning speed response.
you either are
Thanks for helping though!
It is "maths" with an S. Good site for revision however, thanks
Glad you got some value here.
(Maybe it could be "mathematics" with an EMATICS)
