Answer:

Step-by-step explanation:
First, you add 66 to both sides so then the equation you are trying to solve will be: 
Finally, you simplify and get: 
Hope this helped!
<span>M/2=m+1/10
m - m/2 = = -1/10
m/2 = -1/10
m = (- 1/10)(2)
m = - 1/5</span>
F(m) = 2.5 + 0.12m
if Natalie paid $6.82
6.82 = 2.5 + 0.12m
0.12m = 6.82 - 2.5
0.12m = 4.32
m = 4.32 ÷ 0.12
m = 36
The call was 36 minutes long.
2 would most like be doubled and be 4 I think...
