Fluency Practice

A phone company charges $0.05 per text message. Which statement about this situation is correct?

This is an exponential situation because the cost increases each time.

This is a constant rate situation because the same amount ($0.05) is added for each text.

This is a constant percent rate situation because $0.05 is a small number.

This is neither linear nor exponential because the cost depends on usage.
