Answer:
The average rate of change for this sequence is 1
Step-by-step explanation:
The average rate of change is calculated as the slope of the line joining the end points of the sequence.
In this case the end points are;
(-.5, 2.5) and (1,4)
We simply calculate the slope using the gradient formula;
Change in y / change in x
(4 - 2.5)/(1 - -0.5) = 1
Bank A = 1000 x (1 + (0.04*6)) = $1,240
Bank B = 1000 x (1+0.03)^6 = $1,194.05
Bank A would be worth more
Answer: There is no need to round in this case, but 159% of 980 is 1558.2.
