Step-by-step explanation:
A spreadsheet is a useful tool for keeping track of the numbers. A picture of one is attached.
We have assumed that the dollar amount for housing computed in the first part remains the same (though the percentage changes). If that is not the case, you'll have to recompute.
Likewise, we assume that the "5%" retirement amount remains 5% of the nominal salary, rather than 5% of the salary after the mandatory retirement deduction. Similarly, we assume dance lessons remain at their original amount, and were not reduced when the company began taking mandatory retirement.
Feel free to build your own spreadsheet and recompute as needed for any assumptions I got wrong, or for any additional scenarios.
The answer is B as a 90 degree rotation will still keep the same figure.

Answer:
.
Step-by-step explanation:
Let x represent side of kennel opposite to house and y represent other sides.
We have been given that a rectangular dog kennel is to be constructed alongside a house with 60 m of fencing.
Since fencing will cover 3 sides of kennel, so perimeter of kennel would be:


Let us solve for x.


The area of the kennel would be product of its sides that is:

Now, we will substitute
in area equation as:


Let us find the derivative as shown below:

Now, we will set derivative equal to 0 and solve for y.




Upon substituting
in area function, we will greatest possible area.





Therefore, the greatest possible area that can be enclosed by 60 m of fencing is 450 square meters.
