Answer 56

125 - 30%

30% = .3

In order to subtract 30% from 125, we can just multiple 125 by .7

If you take 30% away from the full amount, 125, we are left with the 70%

70% = .7

So, think of it as since we subtracted 30% of 125, what is 70% of 125?

From there, we just do .7 x 125

of means multiply ;p
