Read the t-shirt scenario.  What do you notice / wonder?

Class Notices / Wonderings:

  • Shirts are expensive – the $200 fee is high!
  • I wrote and equation
  • Weird - $200 fee – grays blacks 
  • Why do the colors matter?  Why is it extra for gray? 
  • Lot of little fees add up.
  • $200 big fee. 
  • Why so expensive. 
  • How many shirts was he getting?  
  • $8 per t-shirts and there are 100, why is it $1000? 
  • Why is there a $200 fee 
  • Why were the t-shirts $8, he should get a discount if he buys a lot. 
  • Why are they so expensive? 
  • Expensive! 
  • Fee to begin with, Just ONE t-shirt would cost $208!
  • I was curious about why people don’t include the starting price.  Total listed only 
  • Didn’t say how much was added for the colors.   +1  +1 
  • Tax for all of them or just the on tshirt. 
  • 200 is the constant.  If it is $8 per t-shirt for 100 shirt. So if don’t order 100, is the cost the same?  (discount for more, or more for less shirts)   +1 
  • How many does he want to buy? +1 
  • How much the first time fee wo separation of colors. +1 
  • Why is it so much for the colors.

2.  Write an equation of the line.

3.  Decide how much he should charge for each t-shirt.
