Chapter 2 Review Day 2 Rules • A question will be shown on board. • Everyone will work out the problem on piece of paper. • A name will be draw from a cup. • If you can answer correctly and show your work, then you may play the game. To Play the Game • FYI: You represent your team when you come up to play! • You will choose one card at a time to earn points. • You may choose only 1-5 cards at a time! • If you pick the card with a NINJA SHEEP, then you lose the points for that round (question).

Chris buys DVDs at Best Buy for $5 each. He needs to spend less than $50. Problem 9: Write an inequality that shows the number of DVDs, d, he can buy without spending $50 or more. Chris buys DVDs at Best Buy for $5 each. He needs to spend less than $50. 5 < 50 < 10 Problem 10: Write an inequality that shows the number of gum packs, g, he can buy without spending more than $5. Paul buys packs of Trident gum for $1 a pack and a drink for $2.50. He only has $5 to spend. Problem 10: Write an inequality that shows the number gum packs, g, he can buy without spending more than $5. Paul buys packs of Trident gum for $1 a pack and a drink for $2.50. He only has $5 to spend. $1 + $2.50 ≤ $5 ≤ 2.5 ≤ Problem 11: Write an inequality that shows the number of shoes, x, she can buy without spending more than $30. Mary buys pairs of sandals for $7 a pair and a shirt for $13. She only has $30 to spend. Problem 11: Write an inequality that shows the number of shoes, x, she can buy without spending more than $30. Mary buys pairs of sandals for $7 a pair and a shirt for $13 She only has $30 to spend. $7 + $13 ≤ $30 ≤ 2.428 … ≤ Problem 12: Write the corresponding inequality statement for when Franco is at least 6000 feet from home. Franco is riding his bike to school at a rate of 600 feet per minute. His school is 9000 feet from his home. The graph represents his distance from home over 17 minutes. Problem 12: Write the corresponding inequality statement for when Franco is at least 6000 feet from home. Franco is riding his bike to school at a rate of 600 feet per minute. His school is 9000 feet from his home. The graph represents his distance from home over 17 minutes. ≥ 10 The graph represents the temperature range in a city over 20 hours.
