HSF-LE.A.2

Distinguish situations that grow by equal differences (linear) from those that grow by equal factors (exponential). Model a real choice with linear functions, find the break-even point, and use it to decide. Model growth and decay by a constant percent rate with exponential functions, and interpret the parameters. 3 games practise it.
