If the survey found that 3 out of 8 students owned a pet, we can use this information to create an equation. Let's say "T" represents the total number of students in Mrs. Garcia's class.
Since 3 students out of 8 own a pet, we can represent this fraction as 3/8.
To find the total number of students, we can use the equation:
(3/8) * T = 8 (since there are 8 students who own a pet)
Now, we can solve for T by isolating it:
3 * T = 8 * 8
3T = 64
T = 64/3
So, the equation that models the total number of students, T, in Mrs. Garcia's class is:
T = 64/3 or T ≈ 21.33
