Answer:
The mark up is $21.16 and the final selling price is $44.14
Step-by-step explanation:
To find the mark up price, you simply multiply the cost by the mark up percentage. This will give you the mark up.
$23 * 92% = $21.16
Now to find the total selling price, we add the cost and the mark up together.
$23 + $21.16 = $44.16
Answer:
I need to see the whole question but I believe you just add the numbers
A is incorrect. The identity is for the Sin( A - B). It is not for the Cos(A - B)
B is closer, but NOT the answer. The sign in the middle is incorrect, for one thing. For another Cos(pi/2) = 0,, so the answer would be cos(theta) using this formula.
C The sign is correct in C. The problem is that it is the wrong formula for Cos(theta - pi/2). C should go
Cos(theta - pi/2) = cos(theta) cos(pi/2) + sin(theta)*sin(pi/2)
D. Looks like it's the correct answer. See the comment for C: The identity for C is actually correct for D.
Cos(theta)cos(pi/2) = 0 because cos(pi/2) =0
Sin(theta)*sin(pi/2) = Sin(theta) because Sin(pi/2) = 1
Answer D <<<<<< answer.
