An office has 150 employees, and 30 of the employees work the night shift. What percentage of the employees work the night shift
Zanzabum
<h2>Answer:</h2>

The percent of employees who work in the night shift are:

                                     20%

<h2>Step-by-step explanation:</h2>

Total number of employee in the office are: 150

Number of employee who work in the night shift are:  30

The percent of the employee who work in the night shift is calculated as follows:

\dfrac{\text{Number\ of\ people\ working\ in\ the\ night\ shift}}{\text{Total\ number\ of\ employees}}\times 100

Hence, on putting the value in the above formula we get:

=\dfrac{30}{150}\times 100\\\\\\=\dfrac{1}{5}\times 100\\\\\\=20\%

            Hence, the answer is:

                          20%

Terry’s 7th grade class started out with 40 students. Over the last 4 months the class has seen a 30% decrease in students. How
Rashid [163]

Answer:

28 students

Step-by-step explanation:

30% is equal to .3

40 x .3 equals 12

This means the class has lost 12 students.

40 - 12 is 28.

Another way:

Because the class has lost 30% of it's students, you know that the class is 70% of it's original capacity.

70% is equal to .7

40 x .7 is 28
