189 : 24 = 7 r 21
------------------------
We have a piecewise function.
Therefore, to find the function, we must evaluate each domain separately.
We have then:
For
:
The function for this domain is:

For
:
The function for this domain is:

Where,

Substituting:

For
:
The function for this domain is:
Answer:
Step-by-step explanation:
Principal, P = $4,000
Interest rate, r = 3% = 0.03
Period, t = 20 years
Number of times compounded in a year = 4
Amount , A = P( 1 + r/n)^tn
A = 4000( 1 + 0.03/4)^4*20
A = 4000( 1 + 0.0075) ^80
A =4000( 1.0075) ^80
A = 4000* 1.818
A = $7272.18
