Let \( x \) represent the total points possible for the extra credit project. We know that Mark earned 90% of the total points, which can be expressed as:
\[
0.9x = 108
\]
To find \( x \), we can solve the equation by dividing both sides by 0.9:
\[
x = \frac{108}{0.9}
\]
Calculating the right-hand side:
\[
x = 120
\]
Thus, the total points possible for the extra credit project is \( \boxed{120} \).
\[
0.9x = 108
\]
To find \( x \), we can solve the equation by dividing both sides by 0.9:
\[
x = \frac{108}{0.9}
\]
Calculating the right-hand side:
\[
x = 120
\]
Thus, the total points possible for the extra credit project is \( \boxed{120} \).
