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 a physical condition called "the bends". Suppose the diver started at 82 feet below the surface and rose in five steps of 15 feet each. Use an integer to describe his new position in relation of the water surface.
The diver started at 82 feet below the surface.
After the first step of 15 feet, the diver would be at:
82 - 15 = 67 feet below the surface
After the second step of 15 feet, the diver would be at:
67 - 15 = 52 feet below the surface
After the third step of 15 feet, the diver would be at:
52 - 15 = 37 feet below the surface
After the fourth step of 15 feet, the diver would be at:
37 - 15 = 22 feet below the surface
After the fifth and final step of 15 feet, the diver would be at:
22 - 15 = 7 feet below the surface
Therefore, the diver's new position in relation to the water surface is 7 feet below the surface.
