1. 125,000 x 5% = 6,250
Now you subtract 125,000 by 6,250 because it’s decreasing.
125,000 - 6,250 = 131,250
2. 131,250 x 15% = 19,687.5
Now you have to add 131,250 and 19,687.5 cause it’s increasing.
131,250 + 19,687.5 = 150,937.5
3. 150,937.5 x 20% = 30,187.5
You subtract those two numbers since it’s decreasing.
150,937.5 - 30,187.5 = 120,750
120,750 is your final answer
