Pt = the total number of purple jellybeans in the jar Yt = the total number of yellow jellybeans in the jar T = the total number of jellybeans in the jar Assuming that the scoop Rebecca took represents the total sample there are several quantities that are proportional. S = the total number of jellybeans in the scoop is proportional to T = the total number of jellybeans in the jar, Ys = the total number of yellow jellybeans in the scoop is proportional to Yt = the total number of yellow jellybeans in the jar, and Ps = the total number of purple jellybeans in the scoop is proportional to Pt = the total number of purple jellybeans in the jar. My thinking is that if 15P jellybeans out of a scoop of 90 jellybeans are purple then 58 jellybeans would be out of a jar of 348 jellybeans. If 75 jellybeans were

Unformatted text preview: yellow out of a scoop of 90S jellybeans then 290 jellybeans would be out of a jar of 348 jellybeans. Total number of jellybeans in the jar = 348 jellybeans. I took the constant ratio approach to this problem because I was able to make the quantities proportional by setting up different ratios. Scaling and constant multiplier did not seem to fit as well as constant ratio did in setting up quantities that were proportional to each other. Also the constant ratio approach allowed me to visualize this problem clearer then scaling and constant multiplier did. Ps = the total number of purple jellybeans in the scoop Ys = the total number of yellow jellybeans in the scoop S = the total number of jellybeans in the scoop...
