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

Question

, of the dam last month? What was the water level last month?(1 point)
Responses

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.
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 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.

Answer 1

To find the water level of the dam last month, we can use the given information:

1. The water level last month (let's call it \( w \)) decreased by 8.8 meters to reach the current water level of 95.3 meters.

From this information, we can set up the equation:

\[ w - 8.8 = 95.3 \]

Now, let’s solve for \( w \):

\[ w = 95.3 + 8.8 \]

\[ w = 104.1 \]

So, 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.

Thus, the correct response is:

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