Emily = x
Samantha = x + 2
Lauren = x + 4

x + (x + 2) + (x + 4) = 42

x = 12

Thus: 

Emily = 12
Samantha = 14
Lauren = 16

It takes 20 hours and $400 to interview a candidate
erma4kov [3.2K]

Answer:

Not sure what this question is asking but for the hourly rate, the answer is $20.

Step-by-step explanation:

You can write an equation as 20x=400.

Simply solve it by dividing each side by 20 to find the hourly rate in dollars per hour.

You get x=20 as your answer so 20 dollars per hour!

Hope this helps! :)
