By PEMDAS (or any alternative), <em>the first step should be to divide</em>, as D comes before A. So, 16 ÷ 4.
Answer:
12.625
mean=total sum value /total data set
Step-by-step explanation:
Answer:
We get the value of Principal amount i.e initial investment = $61640
Step-by-step explanation:
Interest rate r = 3.59% or 0.0359
Compounded quarterly n = 4
Future Amount A = 117,300
Time t = 18 years
We need to find initial investment i,e Principal Amount P
The formula used is: ![A=P(1+\frac{r}{n})^{nt}](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
Putting values and finding P
![A=P(1+\frac{r}{n})^{nt}\\117300=P(1+\frac{0.0359}{4})^{4*18} \\117300=P(1+0.008975)^{72}\\117300=P(1.008975)^{72}\\117300=P(1.903)\\P=\frac{117300}{1.903}\\P=61640](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D%5C%5C117300%3DP%281%2B%5Cfrac%7B0.0359%7D%7B4%7D%29%5E%7B4%2A18%7D%20%5C%5C117300%3DP%281%2B0.008975%29%5E%7B72%7D%5C%5C117300%3DP%281.008975%29%5E%7B72%7D%5C%5C117300%3DP%281.903%29%5C%5CP%3D%5Cfrac%7B117300%7D%7B1.903%7D%5C%5CP%3D61640)
So, We get the value of Principal amount i.e initial investment = $61640
The answer for #2 is A
