12. Another one! I had $20, but my mom took away a debt of $5 that I owed Mr. Segerson! Then, I purchased him a $15 gift certificate to Sportsman’s Warehouse. How much money do I have now? $10

13. Are you ready for a REAL difficult one?

14. First, Let’s think back a few months! Translate this! I am thinking of a magic number! That number increase by five and decreased by 6 for a result of 20…. What is my number? X + 5 – 6 = 20 X -1 = 20 +1 X = 21

15. How about this one? Translate this! I am thinking of a magic number! That number increase by five and decreased by 9 for a result of -2…. What is my number? X + 5 – 9 = -2 X -4 = -2 +4 X = 2

16. How about this one? Translate this! I am thinking of a magic number! That number increase by 8 and decreased by 12 for a result of -5…. What is my number? X + 8 – 12 = -5 X -4 = -5 +4 X = -1

17. How about this one? Translate this! I am thinking of a magic number! That number decrease by 3 and increased by 9 for a result of 0…. What is my number? X - 3 + 9 = 0 X + 6 = 0 -6 X = -6

18. How about this one? Translate this! I am thinking of a magic number! That number decrease by 7 and increased by 10 for a result of -2…. What is my number? X - 7 + 10 = -2 X +3 = -2 -3 X = -5

19. How about this one? Translate this! I am thinking of a magic number! That number decrease by 3 and increased by 5 and the decreased by 20 for a result of -2…. What is my number? X - 3 + 5 – 20 = -2 X -18 = -2 +18 X = 16

20. How about this one? I spent some money at Wal-Mart….Let’s call that amount I spent a “magic number”! Then, grandma gave me $10 and I spent $5. I ended up $6 in debt. How much did I spend at Wal-Mart? X +10 - 5 = -6 X +5 = -6 -5 X = -$11 ($11 in debt!)

21. How about this one? I spent some money at Wal-Mart….Let’s call that amount I spent a “magic number”! Then, grandma gave me $20 and I spent $25. I ended up $5 in debt. How much did I spend at Wal-Mart? X +20 - 25 = -5 X -5 = -5 +5 X = $ (Dude, I am broke!)

22. Another one! It was a cold night! At 2:00AM the temperature was 15 below zero! By 8:00 AM, it was 2 degrees below zero, but by noon it was 7 degrees. How far did the temperature raise from midnight until noon? 22 degrees

23. WARM-UP Translate this! I am thinking of a magic number! That number decrease by 8 and increased by 11 for a result of -5…. What is my number? X - 8 + 11 = -5 X +3 = -5 -3 X = -8

24. Another one! It was a cold night! At 4:00AM the temperature was 20 below zero! By 8:00 AM, it was 5 degrees below zero, but by noon it was 3 degrees. How far did the temperature raise from 4:00AM until noon? 23 degrees

25. How about this one? I spent some money at Wal-Mart….Let’s call that amount I spent a “magic number”! Then, grandma gave me $10 and I spent $30. I ended up $5 in debt. How much did I spend at Wal-Mart? -X + 10 - 30 = -5 -X -20 = -5 +20 -X = $15 ( X = - $15 (I spent $15 at first….

26. How about this one? I spent some money …. Then, grandma gave me $15 and I spent $10. Then my mom took a debt away from me for $5 I owed my neighbor. I ended up a dollar in debt. How much did I spend? -X + 15 – 10 – (-5) = -1 X +10 = -1 -10 X = - 11 ( X + 5 – (-5) = -1 Why is this negative? Because I SPENT it!(

27. How about this one? I spent some money …. Then, dad gave me $20 and I spent $10. Then my mom paid back some money I owed to a friend for me… $15! Cool, eh? I still ended up with a dollar. How much did I spend? -X + 20 – 10 – (-15) = 1 X +25 = 1 -25 X = - 24 ( X + 10 – (-15) = 1

28. Another one! (Placing them in an algebraic equation!) I had $20, but my mom took away a debt of $5 that I owed Mr. Segerson! Then, I purchased him a gift certificate to Sportsman’s Warehouse and I ended up with $20…. How much money did I spend on his gift certificate? 20 - (-5) – x = $20 20 +5 – x = $20 25 – x = $20 x = -$5

29. Another one! I had $30, but my mom took away a debt of $15 that I owed Mr. Segerson! Then, I purchased him a gift certificate to Sportsman’s Warehouse and I ended up with $10…. How much money did I spend on his gift certificate? 30 - (-15) – x = $10 30 +15 – x = $10 45 – x = $10 – x = $-35 x = SPENT $35
