3x6-10. The ten is supposed to be abive the six.
So we solve for each
70% of 100=70
students who didn't buy lunch=100-70=30

we know that the students who didn't buy lunch didn't change number so therefor
100% of students left-60%=40%= students that didn't buy lunch=30 so
40%=30
20%=15
100%=75
there were 75 students lfet in the cafeteria
160 x 4 =? ~a~
