Answer:
the answer is x=0 and x=2
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The compound interest formula is
where:
- P is the starting amount called the principle
- r is the rat written as a decimal
- n is the number of times compounded in a year
- t is the number of years
Substitute a value into each variable to solve.
- P = $147 since 10% of 1,470 is being invested which makes P = 0.10(1470) = 147.
- The rate is 3.5% or r = 0.035.
- n = 12 because it is compounded monthly meaning 12 times a year.
- t = 25 since it will earn for 25 years.
![A = P (1+r/n)^{nt}\\A = 147(1 + \frac{0.035}{12})^{12*25}\\A = 147 ( 1 + 0.002916)^{300}\\A = 147(1.002916)^{300}\\A = 352.19](https://tex.z-dn.net/?f=A%20%3D%20P%20%281%2Br%2Fn%29%5E%7Bnt%7D%5C%5CA%20%3D%20147%281%20%2B%20%5Cfrac%7B0.035%7D%7B12%7D%29%5E%7B12%2A25%7D%5C%5CA%20%3D%20147%20%28%201%20%2B%200.002916%29%5E%7B300%7D%5C%5CA%20%3D%20147%281.002916%29%5E%7B300%7D%5C%5CA%20%3D%20352.19)
Repeat this process for each formula.
After the first year at 3% , 150$ would have been added at the end of the year. 5000 x .03 = 150$
