Answer: The initial investment was $ .

Type of calculation: Calculating the original value when we know its percentage part.
How to use the calculator: Use the Original Value CALCULATOR ("What is the original value if X% of it equals Z?"). Enter 20 [X] and $1200 [Z]. It will calculate the total invested amount.
The formula:
We want the initial investment, knowing that 20% of it is $1200.
Formula: Original value = Z / (X / 100)
Initial investment = $1200 / (20 / 100) = $1200 / 0.2 = $6000
