Is there a math formula to reduce a number by percentage over and over, like

100-50%-40%-30% to give a total reduction rate of x%

thanks

what?
like 100*0.5*0.3*0.4*0.3?

not exactly, 100 - 50% = 50 , 50 - 40% = 30, 30 - 30% = 21% therefore total reduction = 79%

i'm saying you cant' just add 50+40+30 and i was hoping there was a way to say something like

Xn+Xn+1 + Xn+2 / 3 = Rate of Reduction

umm...

just do (1-n1)*(1-n2)*(1-n3)... where the ns are your percentages.

This is algebra 1 (maybe 2) level of stuff...

Reducing something by 30% is taking 70% OF it.
