Answer 1

Answer:the possible numbers of minutes she has used her phone in a month is 1044 minutes or more.

Explanation:

Let m represent the number of minutes that she has used her phone in a month.

For her phone service, Jessica pays a monthly fee of $18, and she pays an additional $0.06 per minute of use. This means that for x minutes monthly, her total fee would be

0.06x + 18

The least she has been charged in a month is $80.64. This means that

0.06x + 18 ≥ 80.64

0.06x ≥ 80.64 - 18

0.06x ≥ 62.64

x ≥ 62.64/0.06

x ≥ 1044
