To find the current depth of the scuba diver after she ascends, you can subtract the distance she ascended from her original depth.
The original depth is -75 feet (since it is below sea level), and she ascends 12.7 feet. This can be calculated as follows:
\[ \text{Current depth} = -75 + 12.7 = -62.3 \text{ feet} \]
So, the current depth of the scuba diver is 62.3 feet below sea level.
