1. Proportional or not proportional, and the reason.
1. What is proportional because all the unit rates are equivalent and there exists two CoPs of 1/3 and 3?
100
6. The correct equation to represent the relationship between pounds and cost, and reason why.
6. What is c = 3.50p because the cost equals the number of pounds times $3.50 ($3.50 per pound)?
100
11. Proportional or not proportional graph, and reason.
11. What is not proportional because this line does not pass through the origin?
200
2. The Constant of Proportionality of this table.
2. What is no Constant of Proportionality exists?
200
7. The equation(s) from this list that represents a proportional relationship, and the reason.
7. What is none of these equations because proportional equations do not have addition or subtraction?

8. Given that the cost of two boxes of pasta is $7.00, this is the correct equation to relate cost, c, with number of boxes, b.
8. What is
c = 7/2 b

13. The faster runner (red or green), and the reason.
13. What is red because red covers more distance in less time (the red line is steeper)?

4. The two equations that represent the relationship between the water, w, and time, t.
4. What are t = 1/5 w and w = 5t ?

5. DAILY DOUBLE: The cups of red paint needed with 10 cups of white paint.
5. What is
40/7
or
5 5/7
or 5.71 cups of red paint?
500
10. DAILY DOUBLE: Proportional or not proportional, with proof.
Equation:
y=10/x
10. What is not proportional because if we create a table of values, the ratios are not equivalent, which means no CoP exists?
500
15. The two equations that represent the relationship between the number of stars, s, and the number of flags, f.
15. What are s = 50f and f = 1/50 s ?
