Answer:
1,414 students in the high school are not freshman
Step-by-step explanation:
Since 30% of the high school students are freshman, then the remaining students must be anything but freshmen (sophmores, juniors, seniors). The entire student population must equal 100%, so 100 - 30 = 70% of the students that are not freshman. When calculating with percentages, we must first convert them to decimals by dividing by 100: 70/100 = 0.70. If there are 2020 students in the high school, multiplying the total number by the 70% that are not freshman, will give us the total amount:
2020 x 0.70 = 1,414
