c is the correct answer
Answer:
$7,544.58
Step-by-step explanation:
We will use the compound interest formula provided to solve this:

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 3.3% into its decimal form:
3.3% ->
-> 0.033
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:


The balance after 1 year will be $7,544.58
Answer:
B
Step-by-step explanation:
the money increases hourly so A and C are wrong. and it is constant so the answer is B
(2 - 7z)(2 + 7z)
= (2)^2 - (7z)^2
= 4 - 49z^2
4 = (r-2) t
8 = (r+2) t
4 = (r-2) * [8/(r+2)]
4 = (8r-16)/ (r+2) . . .multiply by 2
4r + 8 = 8r - 16
4r = 24
r = 6
hope this helps
