suppose 7,330 dollars is invested at 14.8% per annum for 10 years compounded monthly, how many dollars will be earned in interes
s2008m [1.1K]

Answer:

$24,580.12

Step-by-step explanation:

Lets use the compound interest formula to solve:

A=P(1+\frac{r}{n} )^{nt}

<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% -> \frac{14.8}{100} -> 0.148

Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:

A=7,330(1+\frac{0.148}{12})^{12(10)}

A=31,910.12

Now subtract that number from our original amount invested:

31,910.12-7,330=24,580.12

<u>The dollars earned in interest is $24,580.12</u>

Please help. I don't understand how to do number 14
murzikaleks [220]
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)
