For her phone service, Ann pays a monthly fee of $16, and she pays an additional $0.05 per minute of use.The least she has been charged in a month is $72.65

what are the possible numbers of minutes she has used her phone in a month use m for the number of minutes, and solve your inequality for m

1 answer

The total cost Ann pays in a month is a combination of the monthly fee and the additional cost per minute of use. We can represent this with the equation:

16 + 0.05m = 72.65

To solve for m, we need to isolate it on one side of the equation. First, subtract 16 from both sides:

0.05m = 72.65 - 16
0.05m = 56.65

Next, divide both sides by 0.05 to solve for m:

m = 56.65 / 0.05
m = 1133

Therefore, the possible number of minutes Ann has used her phone in a month (m) is 1133 or more.
