Learning goals: Teacher Facing Calculate the result of applying a percent increase repeatedly and write the result as a numerical value and expression. Use graphs to illustrate and compare situations in which different percent increases are applied to the same initial value. Write an expression of the form $(1+r)^n$ to represent a percent increase applied $n$ times.
