An environmental agency studying the effects of drought on a lake found that the water level decreased at a constant rate during the first few months of the drought. When the agency began its research, the depth of the lake was 346 feet. The table represents the agency’s susequent observations about the lake's depth.
Which equation represents the depth of the lake, y, based on the number of weeks passed, x?
y = -0.6x + 346
y = -1.2x + 346
y = -0.6x
y = -1.2x

The total number of students who participated in the survey are 100.
Given to us
The number of students who choose other as their favorite subject = 20 students
Math = 30%
English = 45%
Let the total number of students in the survey be x.
We know that percentage is always 100%, therefore,
Total number of students in the survey = other + Math +English
100% = other + 30% + 45%
100% - 30% - 45% = other
other = 25%
Thus, the percentage of students who choose another as their favorite subject is 25%.
We know that the number of students who choose English as their favorite subject in the surveys is 20, therefore,
25% of the total number of students = 20
Hence, the total number of students who participated in the survey is 100.
