  1. Real life and algebra ? When would I use this stuff in my world ?

  2. Algebra useful ? • http://www.youtube.com/watch?v=QCm8fxTAG3Y&feature=related

  3. When do we use this in real life ? • Actually you use algebra all the time. The is no reason why you should get into long complicated answers for this question. Here are some straight up easy answers. • 1) When filling your car up with gas you can use a form of algebra. Lets say you only have $20.00 to spend on gas today and gas is $3.50 a gallon. How many gallons could you buy? • Let x = # of gallons of gas • 3.50x=20.00 • x=5.71 gallons

  4. Algebra in the real world • 2) Lets say you need to buy a NEW XBox 360. You have $800 to spend on everything. You know a new system costs $400 and extra controller $40. Assuming a game costs $60 how many games could you get? • Let x= the number of Games • $800 = $400 + $40 +$60x • 800=460+60x • 360=60x • x = 6 Games

  6. Try to create a real life example • Lets see….you want to order pizza. There is a deal on at Pizza Hut. $10.99 for one 15” and 5 bucks for each additional pizza . What is your total cost ? • Well let n represent the number of pizzas you will order. • 10.99 + 5n • This becomes the algebraic expression.
