This Is very simple.
30m + 50 = 20m + 100
This is the new equation needed to solve for m.
first we must isolate "m".
30m + 50 = 20m + 100
- 50 - 50
30m = 20m + 50
-20m -20m
10m = 50
divide both sides by 10 to isolate "m".
m = 5

Answer:
$12 per hour
Step-by-step explanation:
In order to find her hourly rate we have to find the amount of dollars billed per hour. To do this we can use this expression: ![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D)
Let's use the points (1, 27) and (2, 39) in the expression:
![\frac{39 - 27}{2 -1}](https://tex.z-dn.net/?f=%5Cfrac%7B39%20-%2027%7D%7B2%20-1%7D)
Now let's simplify the expression:
39 - 27 = 12
2 - 1 = 1
The expression simplifies to 12/1, or 12. This means that Brenda is billed $12 every hour she uses her phone.
