7 dollars per week
Explanation:Rate of change = change in balance (dollars)/change in weeks
for (0, 32) and (1, 39)
Rate of change = (39 - 32)/(1 - 0)
Rate of change = 7/1 = 7
For (1, 39) and (3, 53)
Rate of change = (53 - 39)/(3 - 1)
Rate of change = 14/2
Rate of change = 7
Since the rate of change is constant from calculation, then the rate of change of the balance of the student savings account in dollars and cents per week is 7 dollars per week
