It is C. Associative property of multiplication
Answer:
(a) 
(b) 
Step-by-step explanation:
Given

Solving (a): Multiply equation by 5.
Multiply both sides by 5

Open bracket


(b) Solve for y in
and 

Subtract 10x from both sides

Divide both sides by 35


Factorize the numerator:

Express 35 as 7 * 5



<em>When </em>
<em> is solved, the solution will be: </em>

P = $62.10
62.10 = 20 + 0.5 x + 3 + 0.075 x
0.575 x = 39.1
x = 39.1 : 0.575 = 68
Answer: The maximum number of pages is 68.
