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 − 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 need to set up an equation based on the information given.

Let \( w \) be the water level of the dam last month. According to the problem:

• The water level has decreased by 8.8 meters to reach the current level of 95.3 meters.

So, we can write the equation:

\[ w - 8.8 = 95.3 \]

This means that the water level last month was \( w = 95.3 + 8.8 \).

Calculating this gives us:

\[ w = 104.1 \text{ meters} \]

So, the correct response is:

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