A survey of 200 high school students asked about their primary source of news. The results showed that 50% of students use social media, 25% use news websites, 15% watch television news, and the remaining students rely on print newspapers. According to the survey results, how many students cited print newspapers as their primary news source?

Answer: C. 20
First, calculate the percentage of students who rely on print newspapers. Add the given percentages: 50% + 25% + 15% = 90%. The remaining percentage is 100% - 90% = 10%. Finally, calculate 10% of the total number of students surveyed: 0.10 * 200 = 20 students.
