Answer:
4.) a.) 2.01 b.) 404.01
6.) a.) 152.17 b.) 18412.17 c.) 153.14 d.) 18565.60
Explanation:
To solve, use the exponential growth formula
where
= Amount as a function of time
= Original amount
= rate
= period
= time
For question 4, let
So,
So, the second-period interest would be 404.01-402=2.01
Question 6 can be solved using the same formula, but let
So,
The first-period interest would be 18412.17-18260=152.17
For the second-period, use
:
The second-period interest would be 18565.60-18412.17=153.43
