(A) The constraint in the profit is calculated by letting p be equal to zero first,
p = 200k - 500 = 0
k = 2.5
If the number of knives sold is less than 3, then there is no profit.
(B) As more knives are sold, the amount of profit becomes higher.
(C) Yes it is
P = 200k - 500
14000 = 200k - 500 ; k = 72.5
To be able to do so, at least 73 knives should be sold.
Answer: 97 degrees
Step-by-step explanation:
I drew some letters on your attachment to make it easier for you to understand.
To find angle y you need to find angle x first, you do that by doing (180=A+B+C) and you solve for A which is x degrees (A=180-B-C)
When you use angle C you must combine the 26 degrees and 55 degrees because if you use only 55 let's say, that would be the angle for triangle CDB, and we need C for triangle ABC.
So: A=180-42-81 -> A=57 degrees
Now you know Angle A (57 degrees) and Angle ACD (26 degrees)
All you have to do to find Y is to do: y=180-x-26
So y would be: 97 degrees
Keep in mind this is one of two solution methods I can see, if you want me to show you the other one as well just tell me in the comments, you are welcome.

Step-by-step explanation:
No trapezoid is attached; so, I will solve on a general note
The area of a trapezoid is:
Using the attached image as a point of reference;
The parallel sides are: AD (6cm) and BD (12cm)
The height is 4cm
So, the area is:
Answer:
B) 46 ounces
Step-by-step explanation:
1 pound is 16 ounces, so 16*2 = 32 + 14 = 46!
