Answer:
5x+ 4
Step-by-step explanation:
First, put all of the x variables together. So 3x+4x=7x
7x + 4 -2x Since the 2x is negative you can subtract it from 7x and get 5x.
you can not add the four to the 5x because it does not have a matching variable.
So, you have: 5x+ 4

First, let's consider how many cents $3.00 is.
$1.00 = 100 cents, so $3.00 = 300 cents.
We have 300 cents an hour.
There are 60 minutes in an hour, so divide 300 by 60.
300 / 60 = 5
$3.00/h = 5 cents/min
