The population of Burbville is currently 12,500 people. One researcher, Adam, predicts that Burbville’s population will grow by 2% per year. Another, Marcia, predicts that the population will grow by 600 people per year. (For the following problems, use tools, such as Desmos, as you see fit)
Whose prediction - Adam or Marcia - results in a larger population 7 years from now? Justify your response.
Between these two predictions - Adam’s and Marcia’s - will one of them always predict a higher population? Or will the one predicting a higher population switch at some point? Explain.
Suppose that 50 years from now, the population of Burbville is 35,400. Neither Adam nor Marcia’s model predicts this exactly, but one gets closer. Whose? Justify your response.
Recall that Marcia’s model predicts a growth of 600 people per year. Adjust Marcia’s model with the assumption that in 50 years, Burbville’s population is 35,400. Show your work.

Isuck at math ; ^; m a student solved this problem and said the answer is 3 feet. chase had a roll of ribbon that contained 7 7/8 feet of ribbon. he cut off one piece that was 3 5/8 feet long and another piece that was 1 1/4 feet from the roll. how much ribbon was left on the roll? is the student's answer reasonable? yes, the answer is reasonable. no, the answer is not reasonable. it should be about 2 feet. no, the answer is not reasonable. it should be about 13 feet. no, the answer is not reasonable. it should be about 4 feet.
