Calculating Total Pets Owned After Survey Update

A class of fourth-graders collected data on how many pets their classmates owned. They decided to present their findings using a bar graph. The following data was collected:

Number of Pets Owned:

0 pets: 5 students
1 pet: 8 students
2 pets: 7 students
3 pets: 4 students
4 pets: 3 students
5 pets: 2 students

Based on this data, the bar graph shows the number of students who own a specific number of pets. If 2 more students were to participate in the survey, and both claimed to own 3 pets each, what would be the new total number of students that own 3 pets?
