You have a bank account that began with $50.  You withdraw $10 for a hat.  You deposit $100 from your birthday.  You withdraw $30 for a video game.  You earn $20 for doing chores at your aunt’s house and deposit it.  What is your current balance?

50 - 10 + 100 - 30 + 20 = 130

The balance in Sue’s checkbook was –$12.55. The balance in John’s checkbook was –$10.45. Write an inequality to show the relationship between these amounts.

Who owes more? How do you know?

-10.45 > -12.55

Sue owes more, since 12 is larger than 10 she is further in debt

You are traveling a section of the Appalachian Trail in North Carolina and Tennessee.  Your map shows the elevations of your hike.  After multiple days of hiking you want to know your current elevation.  Your hike began at 2500 ft above sea level and traveled up 1200 ft cresting a hill and traveled down 200 ft only to crest another hill that was 1000 ft up.  After resting, you traveled into a slight ravine that was 100 ft below the last point and then finished with a huge climb taking you another 1000 ft to a beautiful view.  What is your current elevation ?

2500 + 1200 = 3700 

3700- 200 = 3500 

3500+ 1000 = 4500 

4500- 100 = 4400 

4400+ 1000 = 5400ft
