Question

Due to excessive heat, the water level in a dam decreased by 8.8 meters last month. Now, the water level is 95.3 meters. Which equation represents the water level, w , of the dam last month? What was the water level last month?(1 point)
Responses

w − 8.8 = 95.3; the water level of the dam last month was 104.1 meters.
w minus 8.8 equals 95.3 ; the water level of the dam last month was 104.1 meters.

w + 95.3 = 8.8; the water level of the dam last month was 104.1 meters.
w plus 95.3 equals 8.8 ; the water level of the dam last month was 104.1 meters.

w + 8.8 = 95.3; the water level of the dam last month was 86.5 meters.
w plus 8.8 equals 95.3 ; the water level of the dam last month was 86.5 meters.

w − 95.3 = 8.8; the water level of the dam last month was 86.5 meters.
w minus 95.3 equals 8.8 ; the water level of the dam last month was 86.5 meters.

Answer 1

To find the water level of the dam last month, we need to set up an equation based on the information provided.

We know that the water level last month decreased by 8.8 meters to reach the current level of 95.3 meters. This can be expressed by the equation:

\[ w - 8.8 = 95.3 \]

Where \( w \) is the water level last month.

To find \( w \), we can rearrange the equation:

\[ w = 95.3 + 8.8 \]
\[ w = 104.1 \]

So, the correct response is:

**w − 8.8 = 95.3; the water level of the dam last month was 104.1 meters.**
