1. Chapter 4 Review
Solving Inequalities

3. Write an inequality for each graph:

6. Do p 215 # 5, 12, 18 & 19

7. Problem solving with inequalities uses the same rules as discussed in the Chapter 3 review. The only difference is that the ‘=‘ sign is replaced by the inequality sign.
The chart at the left shows the number of cans of food collected by a club during the first four weeks of a food drive.
The goal is to collect at least 3000 cans in 5 weeks. How many cans must be collected during week 5 to meet or exceed the goal?
Define the variable
Let # of cans = c
