For her phone service, Maya pays a monthly fee of $27 , and she pays an additional $0.04 per minute of use. The least she has been charged in a month is $86.04 . 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 .

Maya's cost function is C(m), where m is the number of minutes used.
C(m) = 0.04m + 27

We are given C(m) = $86.04. We want her cost function less than or equal to this.
0.04m + 27 <= 86.04

Type this inequality into our search engine, and we get m <= 1476.
