i sent 451,12 $ to a friend. what was the amount before but had to be 12% taken

To find the original amount before 12% was taken, we can set up the problem as follows:

Let the original amount be $ x $.

After 12% is taken, the remaining amount is 88% of $ x $, which equals the amount you sent: 451.12.

Thus, we can write the equation:
\[
0.88 \cdot x = 451.12
\]
Now, solve for $ x $:
\[
x = \frac{451.12}{0.88}
\]

Let me calculate that.

The original amount before 12% was taken is approximately $ 512.64 $.

**Tip**: When calculating percentages, always remember that subtracting or adding a percentage is relative to the original value, not the new one.
