Inequalities
Chua pays a monthly fee of $25 for his phone service, plus $0.05 per minute of use.
Let M = number of minutes Chua uses the phone service.
His monthly cost for the phone service is:
C = 25 + 0.05M
The least he has been charged in a month is $89.40. If we want to know the number of minutes he used the service in that month, then we must solve the inequality:
25 + 0.05M ≥ 89.40
Subtracting 25:
0.05M ≥ 89.40 - 25
Operating:
0.05M ≥ 64.40
Dividing by 0.05:
M ≥ 64.40 / 0.05
M ≥ 1288
He has used his phone service at least for 1288 minutes in a month
