To solve this problem, we need to determine the original number, from which 20% was subtracted to yield 12975.
Let's denote the original number by [tex]\( x \)[/tex].
1. According to the problem, after subtracting 20% of [tex]\( x \)[/tex] from [tex]\( x \)[/tex], the result is 12975:
[tex]\[
x - 0.2x = 12975
\][/tex]
2. Simplify the equation:
[tex]\[
0.8x = 12975
\][/tex]
3. To find [tex]\( x \)[/tex], divide both sides of the equation by 0.8:
[tex]\[
x = \frac{12975}{0.8}
\][/tex]
4. Calculate the value of [tex]\( x \)[/tex]:
[tex]\[
x = 16218.75
\][/tex]
Therefore, the original number was 16218.75.
