Q#22: The correct student and the reason why.
Student A: m = 15s
Student B: s = 15m
Who is Student B because the savings is the DV and the number of months is the IV?
Who is Student B because 15 is the amount of savings per month which means 15 is multiplied by the number of months to get the total savings?

Q#9: DAILY DOUBLE: The equations that represent the proportional relationship between cups of red paint (r) and cups of blue paint (b).
What are r = 0.25b and b = 4r?
400
Q#14: The difference in speed between the sloth and starfish, which travels at 5.3 feet per minute.
What is a difference of 0.7 feet?
400
Q#19: DAILY DOUBLE: The proportional relationships out of these six equations and the reason that they are proportional.
What are equations 2 and 4 because they can be written in y = kx form?
y = kx -----> m = 4.52p -----> CoP = 4.52
y = kx ---> a = b/8 = 1/8 * b ---> CoP = 1/8
