Avi and Benita’s Repair Shop

In this twist on a classic activity, students compare linear and exponential growth in the context of daily payments. One plan increases by $100 each day, while another grows by doubling the previous day’s payment.

This activity is appropriate for students who have studied linear functions but may not have an experience with exponential growth. With that in mind, it makes a great first activity in an exponential functions unit.
