To find the equation that represents the water level, \( w \), of the dam last month, we know that the water level decreased by 8.8 meters to reach the current level of 95.3 meters.
So, we can represent the water level last month as: \[ w - 8.8 = 95.3 \] This can be rearranged to find \( w \): \[ w = 95.3 + 8.8 \] \[ w = 104.1 \]
Therefore, the equation that represents the water level of the dam last month is: \[ w - 8.8 = 95.3 \] And the water level of the dam last month was 104.1 meters.
So the correct response is: w − 8.8 = 95.3; the water level of the dam last month was 104.1 meters.
