Tatiana is thinking about putting $200 in a savings account that earns 4% interest compounded quarterly. She wants to keep that money in the account for 4 years. Which of the formulas below can help her calculate how much money she will have at the end of the 4 years? A. $200(1 + 0.16)1 B. $200(1 + 0.04)4 C. $200(1 + 0.01)16 D. $200(1 + 0.02)8
Total = 200 (1 + .04 / 4) ^ 44
Total = 200 * (1 + .01) ^ 16
The answer is C
Answer:
C. \(200(1+0.01)^{16}\)
Step-by-step explanation:
We are given that,
Initial investment, P = $200
Rate of interest, r = 4% = 0.04
Time period, t = 4
It is required to find the formula for the money which is compounded quarterly.
The compound interest is given by \(A=P(1+\frac{r}{n})^{nt}\)
Substituting the value, we have,
\(A=200(1+\frac{0.04}{4})^{4\times 4}\)
i.e. \(A=200(1+0.01)^{16}\)
Hence, the formula for the money after 4 years is \(200(1+0.01)^{16}\).
