Is there anything that shows the results of the survey? Like a chart/graph or something? It's got to have something like that.
It said: 90 students were surveyed about their favorite subject in school between math and social studies. How many students chose only math as their favorite subject? (3 points).
The chart is: (Social Studies: 32) (20) (Math:)
I tried my best to do the two circles surrounding them.
I was guessing 38 but if that's wrong I'm sorry.
It was 38 because I added it up and it equal 90. What I did is I added up the numbers in the circle (32 and 20) and it equaled to 52. I then add 39 but that equaled 91, so I tried again but this time I added 38 and it equaled 90 so therefore it would be 38 students.
