Answer:
-15.25 feet
Step-by-step explanation:
The reason is that sea level we measure it zero, so above sea level means numbers that are bigger than zero (positive).
In this case, it says that she is scuba diving below sea level, and below sea level number smaller than zero (negatives). There are only two options with negative numbers and they are -14.82 and -15.25. So it has to be one of those two options.
Now, it says that she is more than 15 feet below sea level, to be more than 15 feet means that she is farther than 15 feet of the sea level, it has to be a number that is farther to zero than -15, which is -15.25 feet.
So the answer is -15.25.
