Answer:
$30.80
Step-by-step explanation:
10% of $28 is 2.80 
add 28+2.80=30.80
 
        
             
        
        
        
We want to determine the equation in point slope form for the line that is perpendicular to the given line and passing through the point (5.6) . 
The equation and the point is; 

We know that for two lines to be perpendicular, the product of their slopes should be -1. 
Therefore, the slope of the perpendicular should be; 

The second condition is that the line must pass through the point (5,6) , to do thid, we write the equation of the line in point slope form which is; 

Inserting all values, we have, 

That is the final answer. 
 
        
             
        
        
        
5n + (-6) = -2
add 6 to -2
5n = -2 + 6
5n = 4
divide both sides by 5
n = 4/5
