Kendra wants to know the average height of first-year high school students in her town. She randomly picked 25 male and 25 female students from each of the 10 high schools in her town. From the data she collected, she concluded that the average height of first-year high school students in her town is 5 feet, 7 inches. How many students in total were included in her representative sample?(1 point)

Kendra picked 25 male and 25 female students from each of the 10 high schools, so the total number of students she picked is 25+25 = <<25+25=50>>50 students

If there were 10 high schools, then she picked a total of 10 high schools * 50 students per high school = <<10*50=500>>500 students in total were included in her representative sample. Answer: \boxed{500}.
