Let

x ----> total number of students Lake City Jr. High Students

we have that

12 out of every 18 rides a bus to school

160 ride a bus to school

Applying proportion

18/12=x/160

solve for x

x=(18/12)*160

x=240 total students

so

9 out of every 15 live in Lake City

that means

6 out of every 15 does not live in Lake City

Applying proportion

y -----> students that not live in Lake City

6/15=y/240

solve for y

y=(6/15)*240

y=96

therefore

96 students do not live in Lake City
