Answer:

Grant will make $60 from selling 12 magazines.
Step-by-step explanation:
Let m represent number of magazine sold and A represent amount of money earned.
We have been given that Grant earns $5 for each magazine he sells. So amount earned from m magazines would be 5 times m that is  dollars.
 dollars.
Now, we will equate total amount earned by Grant with A as:

Therefore, our required equation would be  .
.
To find the amount earned by Grant by selling 12 magazines, we will substitute  in our equation as:
 in our equation as:


Therefore, Grant will make $60 from selling 12 magazines.
 
        
             
        
        
        
Answer:
(g - f)(x) = 3x - 33
Step-by-step explanation:
Arrange f(x)= 2x + 13 and g(x) = 5x -20 vertically as shown below:
  g(x) = 5x - 20
 -f(x) = -2x - 13 
----------------------
(g - f)(x) = 3x - 33
 
        
             
        
        
        
The slope is always change in y value over change in x value so if you pick any 2 points on the line you’ll see that the slope is 30/40 and that simplified is 3/4 so the slop is 3/4
