In a survey at a local​ university, 47% of students say that they get less than the recommended eight hours of sleep per night. In a group of 4000 ​students, how many would you expect get eight or more hours of sleep per​ night?

2120 Students

(Sorry if my explanation has more steps then it needs)

Step-by-step explanation:

1% of 4000.

4000/100

=40

47x40=1880

4000-1880 = 2120

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
