There are 250 students in sixth grade
Solution:
Given that, All the students in the sixth grade either walk home or take the bus home after school
From given,
Number of students walk home = 170
Let "x" be the total number of students in school
32% of the students take the bus
Thus, 32 % of "x" takes bus
To find: total number of students in school
Total students = Number of students walk home + number of students takes bus
[tex]x = 170 + 32 \% \times x\\\\x = 170 + \frac{32}{100} \times x\\\\x = 170 + 0.32x\\\\x - 0.32x = 170\\\\0.68x = 170\\\\x = 250[/tex]
Thus there are 250 students in sixth grade
