adeep-sea diver must descend and ascend in short steps to equalize pressure on her body. if the diver rises
toward the surface too quickly, she may suffer from a physical condition called "the bends." suppose the
diver descends to the bottom in three steps of 12 feet each. write and simplify an expression to describe the
diver's change in elevation.

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
