An 8th grade class develops a linear model that predicts the number of cheerios (a small round cereal) that fit on the
circumference of a plate by using the diameter in inches. Their model is chee^rios = 0.56 + 5.11(diameter).
-If the diameter is increased from 4 inches to 14 inches, the predicted number of cheerios will
Increase by about…
A) 10
B) none of these
C) 21
D) 51
E) 72

Question
