is 20% of the original amount equal to 120?

anonymous · Answer

yes?

amistre64 · Answer

are you unsure?  if you have 2 things that are equal, and you add to them and they are still the same.  then you added an equal amount to each

amistre64 · Answer

if they start with amount, k

1% is equal to k/100

and 20% is just 20 of them

20% = 20k/100,  and we know 20% is equal to 120

120 = 20k/100,  solve for k
