Due Friday, May 8
section 2.4 problems

• 1, you do not need to graph this, just plug the numbers into the equation and solve for unknown. Based on the previous paragraph the equation is Km = (1.6)(miles)
• 5
• You have the equation. Plug the values and solve for the unknown. 
• What are the units on 1.25? Remember, k is always a unit rate
• 6 - What does x mean in this case? What does y mean in this case?
• 6a fill out the table
• 6b 
• Enter Market A data into L1 and L2. Enter Market B data into L3 and L4. turn on statplot 1 and 2 (graph points, not points with lines).
• Enter your equation for Market A into Y1. Enter Market B equation into Y2. Don't forget, your equation needs an x in it.
• Set the window so you can see all data. Set xmin = 0, ymin = 0. set xmax and ymax so you can see the largest data values
• Graph it all. If the lines go through the points you did it correctly!
• 6c - hint, you already should have answered this in 6b
• 6d - tell me the answer based on looking at the graph. (slope)
•  7 
• 7a, make the table using the graph to determine what the missing values are. Of course the missing values will not be exact, just make them as close as you can. Pay attention to the units.
• 7b, just like in problem 6b, use the data to create and equation. Remeber:
• step 1, define x and y
• step 2, plug values into x and y and solve for k
• 7c use your equation to solve for a y value
• 7d use your equation to solve for an x value

Due Thursday, May 7

• section 2.3 problem 9, 10, 11 
• section 2.3 additional problems 2, 4a, 4b

Due Wednesday, May 6
section 2.3

• do the investigation, the objective is to develop a conversion factor which can convert cm to in or in to cm
• problems 1, 2 (1 mile = 5280 ft), 3, 4a, 4b, 5a, 5b, 6

Due Tuesday, May 5
section 2.2 problem 5, 6
section 2.2 additional problems problem 2 {use the percent equation, not proportion                   (percent)(whole)=part}, 3, 4

Due Monday, May 4
section 2.1
problems:

• 1
• 2 - All ratios written as fractions must be in most reduced form.
• 5a, 5b, 5c, 5d
• 6 - When writing a ratio you must pay attention to the units. For example: if the units are g/Kg=g/Kg that is OK. However, you can also write this as g/g=Kg/Kg because the units cancel each other so both sides of the ratio are unit-less, which is the same (note: the numerator and denominator must represent the same thing). Problem 6c, you will need to change some units to make this problem work.
• 7a, 7b - Remember that every proportion can be written in 4 different ways.
• 8
• 9
• 10
• 11
