Question

a deep-sea diver must descend and Ascend in short steps to equalize pressure on his body if the diver Rises toward the surface too fast he may suffer from physical condition called the buttons suppose the diver started at 82 feet below the surface and rose in five steps of 15ft each use an integer to describe his new position in relation to the water surface

Answer 1

If the diver started at 82 feet below the surface, we can say that it started at -82ft. Then, it rose in 5 steps of 15ft each, it means we need to add 5 times 15ft to the initial position to know diver's current position:

$-82+5\cdot15=-7$

The integer that describes diver's new position is -7.
