Function would be f(x) = 5x+85
here, x= 15
5(15)+85 = 75+85 = $160

Answer:   addition property of inequality</h3>
================================================
Explanation:
These are the steps to focus on
step 3: -6x - 8 < -2 
step 4: -6x < 6
The move from the third step to the fourth step has us adding 8 to both sides. Therefore, we use the addition property of inequality.
That property has four forms
- If 
 then 
 - If 
 then 
 - If 
 then 
 - If 
 then 
 
It's similar to the idea of starting with a = b, then adding c to both sides to get a+c = b+c 
We add the same thing to both sides to keep things balanced.

Answer:
The original price of the book was $12.50
Step-by-step explanation:
 3x - 0.2(3x) + 10 = 40
30x - 2(3x) + 100 = 400
    30x - 6x + 100 = 400
            24x + 100 = 400
                      24x = 300
                          x = 12.50
