Asubmersible vessel at an elevation of −95 feet descends to 5 times that elevation. what is the vessel’s new elevation?

The new elevation of the vessel will be (-475) feet.  

Step-by-step explanation:

Present elevation of submersible vessel = (-95) feet

Here minus sign denotes the level of vessel below the sea level.

If the submersible vessel descends to 5 times of the present elevation so the level by which the vessel will reach at = 5 × (95) feet

= 475 feet

But the sign will be NEGATIVE because the vessel is descending.

Therefore, the new elevation of the vessel will be (-475) feet.
