To find the current depth of the scuba diver after ascending, you begin with her initial depth of 75 feet below sea level. Since ascending means she is moving upward toward sea level, you subtract the ascent from her initial depth:
\[ \text{Current depth} = \text{Initial depth} - \text{Ascent} \]
Plugging in the values:
\[ \text{Current depth} = 75 \text{ feet} - 12.7 \text{ feet} = 62.3 \text{ feet} \]
Thus, the current depth of the scuba diver is 62.3 feet below sea level.
