First, find what percentage of students had 3 or more by adding up your known percents:
45% + 23 % + 21% + x% = 100%
x = 11%
Since you're given that 96 students had 2 or more, you add up the percentages of 2 and 3 or more:
11 + 21 = 32%
Now set up a proportion that relates it to the whole:

This will allow you to find the total number of students at the school.
Cross multiplying and solving for x results in 300 total students.
Question 1:
45% had one or more absences. 45% of 300 students is
135 students.
Question 2:
As we found before, 11% of students had three or more. 11% of 300 is
33 students.

Answer: LAST OPTION.
Step-by-step explanation:
In order to solve for the variable "x" from the expression
, you need to follow these steps:
1) You need to multiply both sides of the equation by 3:

2) You need to multiply both sides of the equation by 6:
3) Finally, you can divide both sides of the equation by 15:

16 positive and 26 negative.......16 - 26 = -10 <==
