Suppose you have a cellular phone in which you have committed to spend less than $30 on each monthly bill.
Your rate plan costs $20 a month and includes 30 free minutes.
Each additional minute costs $0.40.
-----------------------------
Set up and solve an inequality to determine how many minutes you may use each month to keep your bill under $30.
20 + 0.40x < 30
0.40x < 10
x < 10/0.4
x < 25 minutes
