Carly receives $50 every week for babysitting for her neighbors. She decides to save the money she receives to help pay for a camp she wants to attend next summer. She tracks how much money she saves from babysitting over the course of the year.
A. Explain why Carly's savings over time is an example of linear change.
B. Create a sequence that describes Carly's growing savings each week over the course of 8 weeks.
A. Carly's savings over time is an example of linear change because she receives a fixed amount of money every week ($50) for babysitting, and she saves that money without any fluctuations or changes in the rate of saving. The amount saved increases steadily over time in a straight line, which is characteristic of linear change.
B. Sequence for Carly's growing savings each week over the course of 8 weeks:
$50, $100, $150, $200, $250, $300, $350, $400
