When the schools were opened for the new year, Hendrix's class had 20 new students. However, at the end of the school year, 1/3 of the students in Hendrix class had transferred to other schools. If the number of students that were in Hendrix's class before 20 new students joined was 160, calculate the number of students that were in the class at the end of the year.
How many students were in Hendrix's class after 20 new students joined? ** After 20 new students joined the class at the start of the school year, the number of students increased to 160+20 = <<160+20=180>>180
How many students transferred from the school? ** However, at the end of the year, 1/3*180 = <<1/3*180=60>>60 students had transferred from the school.
How many students remained in the school at the end of the year? ** The total number of students remaining in the school at the end of the year is 180-60 = <<180-60=120>>120
