Answer:
I have to invest $11364.
Step-by-step explanation:
The formula of Compound Interest is:
![A = P(1+(r)/(n))^(nt)](https://img.qammunity.org/2020/formulas/mathematics/high-school/y9qb3j2onnm2tcov3repw5eg4g51lkrxkm.png)
where A = Amount
P = Principle
r = rate
n = Number of Compounding per year
t = total number of year
Here, A = 15000, r = 5.75% = 0.0575, n = 4(quarterly), and t = 5.
Putting all these values in above formula:
![15000 = P(1+(0.0575)/(4))^(4*5)](https://img.qammunity.org/2020/formulas/business/high-school/fp5qtnj19krhwcjxkfhiixjuep3vs1hzh0.png)
⇒
![15000 = P((4.0575)/(4))^(20)](https://img.qammunity.org/2020/formulas/business/high-school/d3fnkuw5hyrfsd0j7i1pvk7rvuzrjq2bn5.png)
⇒
![15000 = P(1.014)^(20)](https://img.qammunity.org/2020/formulas/business/high-school/s935xsuldf6e0aosmp2g8eimn34txp1lmp.png)
⇒
![15000 = P(1.320)}](https://img.qammunity.org/2020/formulas/business/high-school/isqv47iiixrau2nxq7yfrozlzobalnc60v.png)
⇒ P = 11364
Hence, I have to invest $11364 for 5 years.
