Answer:
$24,580.12
Step-by-step explanation:
Lets use the compound interest formula to solve:

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
First, change 14.8% into a decimal:
14.8% ->
-> 0.148
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:


Now subtract that number from our original amount invested:

<u>The dollars earned in interest is $24,580.12</u>
This is quiet simple. i like to use a method my math teacher calls "plug and chug". we know that y= 4x +2
some people call this the substitution method but it has the same concept. now that we know what y equals, we plug it into teh equation:
(4x+2) -x=17
then we "chug it":
4x+2-x=17
then we have to isolate x. add the x's:
5x+2=17
in order to isolate x subtract 2 from both sides:
5x=15
now to isolate again divide both sides with 5:
x=3
so x is 3. bow we plug that into what y is;
y=4 (3) +2
y=14
so:
x=3
y=14
(to double check plug and chug into the first question . if x and y are correct, you will get 17)
