A school took a survey of its students regarding climate change. Among the students, 80% believed that greenhouse gases were responsible for climate change. Of the remaining students, 60% still believed that climate change was real. 75% of the non-believers did not write their name on the survey. What percent of students are non-believers that did write their name?

The percent of students that are non-believers that did write their name is 2%.

Step-by-step explanation:

Given that a school took a survey of its students regarding climate change, and among the students, 80% believed that greenhouse gases were responsible for climate change, while of the remaining students, 60% still believed that climate change was real and 75% of the non-believers did not write their name on the survey, to determine what percent of students are non-believers that did write their name, the following calculation must be performed:

100 - 80 = 20

1 - 0.6 = 0.4

1 - 0.75 = 0.25

20 x 0.4 x 0.25 = X

8 x 0.25 = X

2 = X

Therefore, the percent of students that are non-believers that did write their name is 2%.
