we have the inequality
step 1
Find out the first solution (positive case)
The first solution is all real numbers less than or equal to 1.20
Interval (-infinite,1.20]
step 2
Find out the second solution (negative case)
Multiply by -1 both sides
The second solution is all real numbers greater than or equal to -2.8
the interval [-2.8, infinite)
step 3
Find out the solution to the given inequality
The solution is
[-2.8, infinite) ∩ (-infinite,1.20]=[-2.8,1.20]
the solution is the interval [-2.8,1.20]

Out of 124 students, only 31 students are taught to buy their lunches in the cafeteria.
<u>Step-by-step explanation:</u>
It is given that,
The 25% of 124 students are taught to buy their lunches in cafeteria.
Therefore, the total number of students taught to buy their lunches in cafeteria is 25% of 124.
<u>To find the number of students who are capable to buy lunches in cafeteria:</u>
- Replace the % symbol into the numeric form.
- The % is represented by 1 ÷ 100.
The 25% of 124 students is written as,
⇒ 25×(1/100)×124
⇒ (1/4)×124
⇒ 31
The number of students taught to buy lunches in the cafeteria out of 124 students is 31 students.
