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)

Question

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 − 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 + 8.8 = 95.3; 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 can set up the equation based on the information given. If the water level decreased by 8.8 meters and is currently 95.3 meters, then we can express the water level last month, \( w \), as:

\[ w - 8.8 = 95.3 \]

To solve for \( w \), we add 8.8 to both sides:

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

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

The correct response is:

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