Miriam saved an initial amount of money to buy a concert ticket. She continued to save a fixed number of dollars each week. The table represents the amount of money Miriam had saved at the end of 6 weeks.
It would not let me add the chart, but this kinda what it looked liked
Week: 0 2 4 6
$ Saved: 15 65 315 465
What is the rate of change in the table? and Explain what the rate of change represents in Miriam's situation?
