Answer:
<em>She will pay $1,047.12 interest for one year</em>
Step-by-step explanation:
<u>Simple Interest</u>
Occurs when interest is calculated on the original principal only.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance or loan
r = interest rate
t = time
Samantha takes out a loan for $17,452 at r=6%=0.06 simple interest for t=1 year. Calculating the interest:
I = $1,047.12
She will pay $1,047.12 interest for one year
First we are going to find the Area of the pond using the area of a circle formula: 
where
is the area of the circle
is the radius of the circle
We know for our problem that the pond will have a 6-foot radius, so
. Lets replace that value on our area formula:
We know that the <span>cost of installing the pond is $0.62 per square foot, so lets multiply the area we just found by the cost:
Total cost of pund=</span>
dollars
Now, let
be the width the rectangle, so its length will be 
. Remember that the area of a rectangle is width times length, so:
Since the cost of installing ties is $1, the cost of installing ties in our rectangle will be x^2+13x dollars.
<span>Stacy can spend no more than $536 on this project, so we can setup an inequality relating the cost of the pound and the cost of installing ties:
</span>
We can conclude that the inequality that can be used to fin the width,, of the patio is
