Answer:

The equation is [tex]40+0.15m = 58.00[/tex] whose solution is [tex]m =120\:minutes.[/tex]

Step-by-step explanation:

Let us call [tex]m[/tex] the number of minutes the phone is used over 200 minutes, then we have

[tex]\boxed{40+0.15m = 58.00}[/tex] (this says monthly bill of $40 plus the cost of phone usage over 200 minutes must equal $58 )

This equation can be used to solve for  [tex]m[/tex] u as follows:

[tex]0.15m = 58-40[/tex]

[tex]m = \dfrac{18}{0.15}[/tex]

[tex]\boxed{m = 120\:minutes}[/tex]
