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
In this graph, we see Chelsea types 50 words per minutes.
To find the answer, I will use tree diagram:
50 words in 1 minute
175 words in ?minutes
Step 1:
Cross multiply
175×1=175
Step 2:
Use division
175÷50=3.5 or 3 1/2 minutes. As a result, Chelsea types 175 words in 3.5 minutes or 3 1/2 minutes. Hope it help!
