I will do an example.  
Say the percentage is 3 and the total is 220

220 is 3% of what number or ‘x’

You do the following equation:    3/100 = 220/x
You cross multiply getting the equation:  3x = 220(100)
  3x = 22000

Then you divide 3 into 22000 to get ‘x’ which would equal 7333.33

The problem statement is ambiguous. It isn't clear whether the given percentage is of the total, or whether it was added to the original amount to get the total.

Oddman, you are correct, and I have seen your activity on this site and you your knowledge of math is amazing. I just assumed that when he/she said 'the total' is 220 that they meant the total of the percentage.
