To find the rate of change, we need to calculate the change in total cost for each additional month.
Change in total cost from 9 to 11 months: 519 - 431 = 88
Change in total cost from 11 to 13 months: 607 - 519 = 88
Change in total cost from 13 to 15 months: 695 - 607 = 88
Since the change in total cost is constant at 88 for each additional 2 months, the rate of change is:
Rate of change = 88 / 2 = 44
Therefore, the rate of change for the health club charges is 44.
A health club charges a one-time sign-up fee and a monthly membership fee. The table below represents what the health club charges. Find the rate of change.
