A popular cellular phone family plan provides 1,500 minutes. It charges $90.00/month for the first two lines and $10.00/month for every line after that. Unlimited text
messages for all phone lines costs $30.00/month, and Internet costs $10.00/month
per phone line. If a family with a $200 monthly budget buys this plan and signs up for
unlimited text messaging and Internet on each phone line, how many cell phone lines can they afford? Use an inequality to solve this problem.
