If the northern side has length x and the east and west sides have length y, then the cost of the fence is 
<span>C = 12x + 12y + 6y </span>
<span>and the enclosed area is A = xy. </span>

<span>12x + 18y = 6000 </span>
<span>x = 500 - 1.5y </span>
<span>A = 500y - 1.5y^2 </span>

<span>A is maximized when y = 500/3. In which case x = 250. </span>

Purchasing discount points is a decision which can be financially justified or not justified. Create a unique example where purc
Semenov [28]
 <span>I believe this question is referring to purchasing a discount on a loan's interest rate by putting more towards closing costs. For mortgages, sometimes they will allow you to "buy" a smaller interest rate. For example: 
Loan A has an interest rate of 4.5% and no closing costs. 
Loan B has an interest rate of 4.375%, but has $1000 in closing costs. 

Normally, Loan A would be the better choice if you plan on keeping the home short term, but Loan B would be more beneficial for keeping the loan long-term. I don't really care to spend the time that is necessary to come up with an actual scenario, but I hope that helps enough for you to understand the question</span>
