Fred's basement is flooded. The basement floor is
\[3.4\] meters below ground level. The top of the water is
\[2.2\] meters below ground level.
The following equation describes this situation.
\[-3.4+1.2 = -2.2\]

A
The top of the water is
\[1.2\] meters above ground level.
(Choice B) The water is
\[1.2\] meters deep.
B
The water is
\[1.2\] meters deep.
(Choice C) The top of the water is
\[1.2\] meters below ground level.
C
The top of the water is
\[1.2\] meters below ground level.
Apologies for the confusion. You are correct. The correct answer is B. The water is 1.2 meters deep.
the correct answer was B
To understand what the value of 1.2 tells us in this situation, let's break down the given equation: -3.4 + 1.2 = -2.2.
The term -3.4 represents the basement floor's position below the ground level, and the term -2.2 represents the top of the water's position below the ground level.
By rearranging the equation, we can isolate the term 1.2: 1.2 = -2.2 - (-3.4).
Simplifying the right side of the equation, -2.2 - (-3.4) becomes -2.2 + 3.4, which equals 1.2.
Therefore, 1.2 represents the difference in height between the basement floor and the top of the water. Based on this, we can determine that the correct answer is:
(Choice A) The top of the water is 1.2 meters above ground level.
