Question
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 − 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 86.5 meters.
w plus 8.8 equals 95.3 ; 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 104.1 meters.

Answer 1

If w was the level last month, subtracting the 8.8 m decrease gives the current 95.3 m: w − 8.8 = 95.3.
Solve: w = 95.3 + 8.8 = 104.1 meters.
