How many students had 3 or more absences? Add together {45%, 21%, 23%} and subtract that sum from 100%: 11%.
How many students had two or more absences? Add together this 11% and 21%: 32% had two or more absences. Let the total number of students be n. Then 32% of these n students add up to 96 students. Thus, 0.32n = 96, and n= 300.
How many students had one absence? The chart shows that that is 45%, and we know that there are 300 students total.
Thus, the number of students who had one absence was 0.45(300) = 135.

Step-by-step explanation:
23.64112 > 23.6404
Reason : 1/1000 place value in 23.64112 is 1.
1/1000 place value in 23.6404 is 0.
X=20. By using the bottom sides of each figure, you can calculate that the figure on the right is 3 times larger than the similar figure on the left. This means that 2x+5=45. When solved, this yields x=20.
