4 2) Autumn lost 3 spaceships in level 3 of a video game. She lost 30 points for each space ship. When she completed level, she earned a bonus of 200 points. By how much did her score change? 3) One month Owen made 3 withdrawals for $20 and 1 withdrawal for $80 from his account. How did the withdrawals change the amount in his account? Solution: 4) Franklin was charged $140 plus a pickup charge of $20 to ship four identical boxes by Fast Ship. The pickup charge applies regardless of how many boxes are picked up. What would have need the change to Franklin s account if he had shipped just 1 box? Solution: 5) Shana took a test with 50 questions. She lost 2 points for each of the 5 questions she got wrong. She got all 3 extra credit questions cored and received 5 points for each. What is the total number of points she gained or lost overall? Solution: 6) When you solve a problem involving money, what can a negative answer represent? Group Work (20 minutes) Level A #s 1-11 Level B #s 1-14

5 Evaluate each expression. Level c #s (-3) (-6) (-60) (-11)(-7) (-7) (-2) (-8) (-9) + 4(-5) (-3) Lily and Rose are playing a game. In the game, each player starts with 0 points and the player with the most points at the end wins. Lily gains 5 points two times, loses 12 points, and then gains 3 points. Rose loses 3 points two times, loses 1 point, gains 6 points, and then gains 7 points. a) Write and evaluate an expression to find Lily s score. Expression: Answer: b) Write and evaluate an expression to find Roses score. Expression:

6 Answer: c) Who won the game? 11. Write and expression from the description. Then evaluate the expression. a) 8 less than the product of 5 and -4. Expression: Answer: b) 6 more than the quotient of -36 and -4. Expression: Answer: 12. Arlene has a gift card for a local lawn and garden store. She uses the gift card to rent a tiller for 4 days. It costs $35 per day to rent the tiller. She also buys a rake for $9. a) Find the change to the value on her gift card. b) The original amount on the gift card was $200. Does Arleen have enough left on the card to buy a wheelbarrow for $50? Explain. 13. Carlos made up a game, where in a deck of cards, the red cards (hearts and diamonds) are negative and the black cards (spades and clubs) are positive. All face cards are worth 10 points, and the number of cards are worth their value.

7 a) Samantha has a king of hearts, a jack of diamonds, and a 3 of spades. Write and expression to the find the value of her cards. Expression: Value: b) Warren has a 7 of clubs, a 2 of spades, and a 7 of hearts. Write an expression to find the value of his cards. Expression: Value: c) If the greater score wins, who won? d) If the player always gets three cards, describe two different ways to receive a score of 7. One Way: Second Way: 14. Write a real world problem that the expression 3(-7) = -6 could represent. 15. Jim found the quotient of two integers and got a positive integer. He added another integer to the quotient and got a positive integer. His sister Kim says that all the integers Jim used to get this result must be positive. Do you agree/disagree? Explain.

8 16. Lisa is standing on a dock beside a lake. She drops a rock from her and into the lake. After the rock hits the surface of the lake, the rock s distance from the lake s surface changes at a rate of -5 inches per second. If Lisa hold her hand 5 feet above the lake s surface, how far from Lisa s hand is the rock 4 seconds after it hit the surface. Answer: Name: Ms. Napolitano Date: Activity #
