Chapter 4 Review Solving Inequalities

Write an inequality for each graph:

Do p 215 # 5, 12, 18 & 19

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 2. No diagram needed here 3. Write an abbreviated word equation 702 + 470 + 492 + 547 + c must be at least 3000 4. Write a mathematical equation 702 + 470 + 492 + 547 + c ≥ 3000 5. Solve the equation c ≥ 789
