Answer:
$24.35
Step-by-step explanation:
We will use the compound interest formula provided to solve this problem:

<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 1% into a decimal:
1% ->
-> 0.01
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:


Lastly, subtract <em>A </em>from the principal to get the interest earned:

Last one is your answer.
X cannot be repeated, but y can
Answer:
a = ±23
Step-by-step explanation:



Answer:
^algebra^
#1). a - b=4
a=4 + b .....(equation 1)
#2) a + b=12
(4 + b) + b= 12
4 + b + b=12
4 + 2b=12
2b= 12 - 4
2b =8
b= 8:2
b=4
subtituted b in equation 1
a= 4 + b
a= 4 + 4
a=8
so, the number is 8 and 4
