If 19300 dollars is invested at an interest rate of 10 percent per year, find the value of the investment at the end of 5 years for the following compounding methods, to the nearest cent.

(a) Annual: $  
(b) Semiannual: $  
(c) Monthly: $  
(d) Daily: $



To find the future value of the investment using different compounding methods, we can use the formula for compound interest:

\[
A = P \left(1 + \frac{r}{n}\right)^{nt}
\]

Where:
- $A$ = the amount of money accumulated after n years, including interest.
- $P$ = the principal amount (initial investment).
- $r$ = annual interest rate (decimal).
- $n$ = number of times that interest is compounded per year.
- $t$ = the number of years the money is invested.

Given:
- $P = 19300$
- $r = 0.10$
- $t = 5$

Now we can calculate for each compounding method.

### (a) Annual Compounding ($n = 1$)
\[
A = 19300 \left(1 + \frac{0.10}{1}\right)^{1 \times 5} = 19300 \left(1 + 0.10\right)^{5} = 19300 \times (1.10)^{5}
\]
\[
A = 19300 \times 1.61051 \approx 31059.84
\]

### (b) Semiannual Compounding ($n = 2$)
\[
A = 19300 \left(1 + \frac{0.10}{2}\right)^{2 \times 5} = 19300 \left(1 + 0.05\right)^{10} = 19300 \times (1.05)^{10}
\]
\[
A = 19300 \times 1.62889 \approx 31406.17
\]

### (c) Monthly Compounding ($n = 12$)
\[
A = 19300 \left(1 + \frac{0.10}{12}\right)^{12 \times 5} = 19300 \left(1 + 0.00833\right)^{60} = 19300 \times (1.00833)^{60}
\]
\[
A = 19300 \times 1.64701 \approx 31804.45
\]

### (d) Daily Compounding ($n = 365$)
\[
A = 19300 \left(1 + \frac{0.10}{365}\right)^{365 \times 5} = 19300 \left(1 + 0.00027397\right)^{1825} = 19300 \times (1.00027397)^{1825}
\]
\[
A = 19300 \times 1.64872 \approx 31809.86
\]

### Summary of Future Values
- (a) Annual: **$31,059.84**
- (b) Semiannual: **$31,406.17**
- (c) Monthly: **$31,804.45**
- (d) Daily: **$31,809.86**
