Create and solve one-variable equations and inequalities from contexts using all studied expression types, including simple root functions.
Choose the one-variable model type that best fits a context
Problem
What type of one-variable model best fits this context? A quantity grows by the same percent each year.
Big Picture
What this problem is really about
Classify a model by the operation that repeats over equal intervals. A fixed amount added each year points to constant additive change, while a fixed percent makes each new value a constant multiple of the previous one. Repeated multiplication places time in an exponent and identifies the matching model family.
