125000 decreased by 5%, increased by 15% then decreased by 20%

125000-5%+15%-20%=

5%*125000=6250

125000-6250=118750

118750*15%=17812.5

118750+17812.5=136562.5

136562.5*20%=27312.5

136562.5-27312.5=109250

Answer=109250

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
