Answer:
43.407 years
Step-by-step explanation:
Zoe invest $600 in college savings account. The account earns 5.7% interest compounded quarterly. How many years will it take for Zoe's account to reach $7,000?
We are asked to find time t in a compound interest formula
The formula is given as:
t = log(A/P) / n[log(1 + r/n)]
A = Total amount = $7000
P = Principal = $600
n = number of times interest is compounded = Quarterly =4
r = Interest rate = 5.7% = 0.057
Hence,
t = log(7000/600) /4[log (1 + 0.057/4)]
t = 43.407 years
14.99% of 2000 is 299.80
Given:
whole amount = 2,000
percentage of the part = 14.99%
find the value of the part.
We simply multiply 14.99% to the whole of 2,000 to get the corresponding value of the part.
2,000 x 14.99/100 = 299.80
To check:
299.80 / 2,000 = 0.1499 x 100% = 14.99%
299.80/0.1499 = 2,000
