Ugh I hate these... Inverse property of multiplication.
Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.
Step-by-step explanation:
1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.
2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.
-5/12 would be the answer
(4x-5)+(2x-3)
4x+2x= 6x
-5+-3= -8
6x-8
Answer:
Step-by-step explanation:
Given that:
R(x) = 
+ 34x − 17
As we know that derivative of revenue function is marginal revenue function .
We will use following rules of derivative
=> dR/ dx = 
=> R' (x) = 
=> R '(2000) = 
= 34
The revenue when 2000 units are sold is:
R(2000) = 
+ 34*2000 − 17 = $69,783
