2.  Jonny has to buy 220 notebooks for his club he is in charge of. 4 notebooks come in one pack for 2.00 each. How much money does he have to get to have enough books for everyone.

3. Y=.50x or f(x)=.50x X=220 Y=The cost of one notebook X=The total number of notebooks needed

4. The independent variable is X (the coast of one notebook) The dependent variable is Y (the number of books needed) The total cost of the notebooks DEPENDS on the number of notebooks.

5. Yes, because all of the X’s (the independent variable) are different.

6. Domain: is the X values Range: is the Y values Domain:(1,50,100,200,220) Range:(220,11000,22000,44000,48400)

7. Yes it is, because you can only purchase the notebooks in groups of 4

8.  Yes because none of my coordinates are the same. They are all different (x)

10.  So however many notebooks Jonny wants depends on how much he will have to pay. It would cost 2.00 dollars for 4. If he buys enough for he buys enough for his club he will spend $110.00 dollars.
