Can plz me in this question asap i don't get it

-19+-25f≤-144

Step-by-step explanation:

The problem says that you descended 19 below sea level. Below makes 19 into a negative. It also says that it descends 25 feet per minute. If it says per you put a variable by that number. It also says descends which means going down so that would be a negative. The problem says Lainey does not want to go over 144 feet(144 is also negative because it is below sea level) so 144 would be greater than or equal to because she does not wan to go over that amount.

Hope this helps!
