152 is your answer

Step-by-step explanation:

Answer:

They are 152 feet underground.

Step-by-step explanation:

Based off of 0 being sea level, or ground level:

They started 84 feet underground. So that is -84 [feet].

They took an elevator 123 feet down. So that is -123 [feet].

... And then they rode mine carts 55 feet back up. So that is +55 [feet].

Now all we have to do is add them up!

(-84) + (-123) + 55 = ?

|_______|

     -207       + 55 = ?

        |_______|

             - 152       = ?

So they are 152 feet underground!

I hope this helps!
