110,000 x 0.2 = 22000 (0.2 is 20% as a decimal, we needed to convert it to multiply it)
So we must add 22000 to 110,000, then take 20% of the new cost, and repeat.
Add them 110,000 + 22000 = 132000
Take 20% of new value 132000 x 0.2 = 26400
Add that 132000 + 26400 = 158400
Take another 20% of that 31680
Add them 158400 + 31680 = 190080
So the value is now $190,080
A much more efficient way to do this would be multiplying 1.2 instead of 0.2, and skipping the adding part, as you already took 100% of it and are adding 20% more.
