Answer:

m > = 1204 minutes

Step-by-step explanation:

28 + 0.05m>=88.20

Answer:

The answer is 1204 minutes.

Step-by-step explanation:

First, take away the monthly fee of 28$ of 88.20$. This gets you 60.20$. Then you divide by 0.05$ because this is how much for each minute. 60.20$/0.05$= 1204. Meaning it is 1240 minutes.

88.20-28= 60.20

60.20/0.05= 1240

Hope these formulas help! (:
