The only restraints on profit result from the restriction on the domain which in turn place a restriction on profit.  
0≤k. Knives sold cannot be negative.
So the range of profit or p is:
p=[-500, +oo)
Profit increases as the number of knives sold increases.  $200 more profit is gained by each sale of a knife.
4000=200k-500
4500=200k
k=22.5
Since k is for knives sold, it must be an integer value, so a $4000 profit is not possible.  At 22, p=3900 and at 23, p=4100

Answer:
The triangle is obtuse, and isosceles. 
Step-by-step explanation:
The triangle is obtuse because there is an angle above 90 degrees, which  is 104 degrees. The triangle is also isosceles due to the two lines in the triangle which indicate that the size of each side are equal to each other. For a triangle to be isosceles, there have to be at least two sides equal to each other, and in this case the triangle has those two equal sides.

The cost for carpeting 20 square yards is $230.
Further explanation:
First of all, we will calculate the cost for one square yard then will find the final answer.
So,
Given
Total area = 28 square yards
Cost of carpeting 28 square yards = $322
Cost of carpeting one square yard = 322/28 = $11.5 per square yard
Now to find the cost of carpeting 20 square yards
Cost of 20 square yards = 20*11.5
= $230
The cost for carpeting 20 square yards is $230.
