Answer:
E.) 1
Step-by-step explanation:
Firstly we will solve for L.H.S.
L.H.S. =
Since we know that
is the inverse of
.
So we can say that;

Now For R.H.S.

Since we can rewrite
as
.
Now we can say that the R.H.S. is;

Now we add the fraction and get;

Now according to trigonometric identity;

So, 
Here,
and
=
<em> </em>
L.H.S. = R.H.S.
Hence 
8 - 5p = 2 - 3p
Move the terms
= -5p + 3p = 2-8
Collect like terms (calculate)
= -2p = -6
Divide both sides
p = 3 (Final Answer)
Answer: She will pay $64.90 in total.
Step-by-step explanation: The bill at the restaurant comes to $55 and Crystal wants to include an 18% tip.
So you will convert this into decimal form, which will be 0.18.
Now, you will multiply 55 by 0.18, giving you 9.9.
Add that to 55 and you will have your answer.
Have a great day!
