Answer:
$1,577.74
Step-by-step explanation:
You are going to want to use the continuous compound interest formula, which is shown below.

<em>A = total
</em>
<em>P = principal amount
</em>
<em>r = interest rate (decimal)
</em>
<em>t = time (years)
</em>
<em />
First change 3% to its decimal form:
3% ->
-> 0.03
Next, we can plug in the values into the equation:


The last step is to subtract 8,000 from 9,577.74:

The total interest earned is $1,577.74
yes, 50 is the correct answer
X+x+1+x+2=57
3x+3=57
3x=54
x= 54/3
x= 18
x+1= 19
x+2= 20
Therefore 20 is the largest
1/3^5
When multiplying exponents you just add them. X^a x X^b = X^a+b
If you have a negative exponent, you flip it to be the denominator (if originally numerator) or numerator (if originally denominator.
So, 3^-5 = 1/3^5
