Answer:
(a)His monthly Interest Rate=0.8%
(b)Annual Interest Rate = 9.6%
(c)![500(1.008)^m](https://tex.z-dn.net/?f=500%281.008%29%5Em)
Step-by-step explanation:
For a Principal P invested at a yearly rate r, compounded m times in t years
Amount at Compound Interest= ![P(1+\frac{r}{m})^{mt}](https://tex.z-dn.net/?f=P%281%2B%5Cfrac%7Br%7D%7Bm%7D%29%5E%7Bmt%7D)
Comparing with Jerry's equation y=388 (1.008)
(a)His monthly Interest Rate= 0.008=0.8%
(b)Annual Interest Rate= Monthly Interest Rate X 12 =0.8 X 12 = 9.6%
(c)If I invest $500 at the same rate of return,
Total Money after m months
= ![P(1+\frac{r}{m})^{mt}](https://tex.z-dn.net/?f=P%281%2B%5Cfrac%7Br%7D%7Bm%7D%29%5E%7Bmt%7D)
![=500(1+0.008)^{m}](https://tex.z-dn.net/?f=%3D500%281%2B0.008%29%5E%7Bm%7D)
![=500(1.008)^m](https://tex.z-dn.net/?f=%3D500%281.008%29%5Em)
Answer:
<u>B</u>
Step-by-step explanation:
If a population is the entire school faculty, a sample of the population could be math teachers.
Always remember a sample is a part of the larger group.
72/6+ 85/6
= (72+ 85)/6
= 157/6
= (156+1)/ 6
= 156/6+ 1/6
= 26+ 1/6
= 26 1/6
The final answer is 26 1/6~
