Homework for Friday, December 13th

In class you received a copy of the graphing paper.  Use that to graph the following questions, we will review this on Monday.


1.) Jennifer is buying tickets for 6 flags.  Each ticket is on sale for $40.  She doesn't know how many people are going but wants to figure out how much she will spend.  Make a table showing the cost of 1 ticket up to 10 tickets.  Graph the results and draw the line.  For your y-axis, count by 10s.


2.) Jessica is going to buy Yu-Gi-Oh cards.  She pays $12 for 4 packs.  Find how much each pack costs.  Make a table showing the cost of 1 pack up to 8 packs.  Graph your results and draw the line.


3.)  Katy paid $12 for 3 chicken sandwiches and $20 for 5 sandwiches.  Create a table showing the cost of 1 chicken sandwich up to 12 chicken sandwiches.  Graph your results and draw the line. Label your x and y axes.

On Graph 3A, count your y-axis by 1s
On Graph 3B count your y-axis by 4s
Circle the Unit rate.
What is the difference between the graphs?  Why do they look different even though they display the same data?

4.)  Oscar bought some hot dog buns for his bbq.  He bought 4 packs and they came with 32 buns.  How many buns are in each pack?  Create a table showing how much it costs for one pack of hot dog buns up to 6 packs of hot dog buns.  Graph your results and circle the unit rate.


5.)  Andres  paid $1 for 4 pencils and $5 for 20 pencils.  Create a table showing the cost of 1 pencil  up to 12 pencils.  Graph your results and draw the line. Label your x and y axes.   

On Graph 5A, count your y-axis by 0.50s
On Graph 5B, count your y-axis by 1s
On Graph 5C, count your y-axis by 2s
Circle the Unit rate.
What is the difference between the graphs?  Why do they look different even though they display the same data? Explain which one would be the best graph to use for this problem.
