DIA and a randomly selected 25% of the seventh grade students and ask her favorite ice cream flavor of the students surveyed 60 students chose vanilla as their favorite based on the data what is the most reasonable prediction of the number of seventh graders in her

236 students.

Step-by-step explanation:

It means that 60 students represents 25% of the seventh grade class plus DIA, which is another student.

From the above we can infer that 59 students are 25% of the class.

Therefore the total number of students, we check it by a rule of three, like this:

total students            % of students

          59                           0.25

           X                               1

Therefore X is the same:

X = 1 * 59 / 0.25 = 236

Which means that in the seventh grade class there are a total of 236 students.
