I will report files and unhelpful answers! For his phone service, Frank pays a monthly fee of $28, and he pays an additional $0.05 per minute of use. The least he has been charged in a month is $88.20.

What are the possible numbers of minutes he has used his phone in a month?
Use for the number of minutes, and solve your inequality for.

m > = 1204 minutes

Step-by-step explanation:

28 + 0.05m>=88.20

Subtract 28 from both sides. Then divide both sides by 0.05 to get:  

m >=1204 minutes

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! (:
