Amalia is scuba diving at a position 24.25 feet below sea level. she descends 0.5 foot each minute for 25 minutes what is amalias position compared to sea level after 25 minutes

We can represent her initial position as -24.25, since it says she is 24.25 feet below sea level.
If she descends -.5 feet per minute, all we have to do is multiply -.5 by 25, and add it to her initial position to get the answer.
-.5*25=-12.5
-24.25+-12.5=-36.5
Her current position is -36.5
Hope this helps!
