32% of the students take the bus
170 students walk home.
How many students are in the sixth grade?

Answer 1

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

`x = 170 + 32 \% * x\\\\x = 170 + (32)/(100) * x\\\\x = 170 + 0.32x\\\\x - 0.32x = 170\\\\0.68x = 170\\\\x = 250`

Thus there are 250 students in sixth grade
