Responses

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.

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 104.1 meters.

To find the water level of the dam last month (w), we know that the current water level is 95.3 meters and that it decreased by 8.8 meters. So the equation that represents the water level of the dam last month is:

\[ w - 8.8 = 95.3 \]

To solve for w:

Add 8.8 to both sides of the equation: \[ w = 95.3 + 8.8 \]
Calculate: \[ w = 104.1 \]

So, the water level of the dam last month was 104.1 meters.

Thus, the correct response is:

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