1. Start with the expression:
+2 - 4 + 5 - 4
.
2. First, add
+2
and
-4
:
2 - 4 = -2
.
3. Then, add the result to
+5
:
-2 + 5 = 3
.
4. Finally, subtract
-4
:
3 - 4 = -1
.

A popular cell phone family plan provides 1500 minutes. It charges 89.99/month for the first 2 lines and 9.99 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. Graph your solution on the number line and explain the meaning of your graph in a sentence.
