Question

For her phone service, Yolanda pays a monthly fee of $29, and she pays an additional $0.04 per minute of use. The least she has been charged in a month is
$72.36.

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.

Answer 1

Let the number of minutes be m
29 + 0.04m ≥ 72.36
0.04m ≥ 72.36 - 29
0.04m ≥ 43.36
m ≥ 1084 minutes
