During a staff meeting, one department director reports that 24 people, representing 30% of department personnel, are
providing customer service that exceeds the company's standards.
How many people work in that department?
34
80
125
720
800

80

Step-by-step explanation:

The easy way to solve this is to find what 1% of the department is and then to multiply by 100, so:

30% = 24

30% / 30 = 24 / 30

1% = 0.8

1% * 100 = 0.8 * 100

100% = 80

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
