Option D:  is the solution
 is the solution
Explanation:
The given expression is 
We need to determine the solution of the expression.
<u>Solution:</u>
The solution of the expression can be determined by solving the expression for the variable x.
Thus, we have,

Adding both sides of the expression by 1, we get,

Dividing both sides of the expression by 3, we get,

Thus, the solution of the expression is 
Hence, Option D is the correct answer.
 
        
             
        
        
        
Answer: 98.90
Step-by-step explanation:
115*.2=23
115-23=92
0.075*92=6.9
6.90+92=$98.90
 
        
             
        
        
        
.88, .90, .92 
when you need to find a decimal of a percentage. start at the percentage sign and move the decimal point two places to the left.. 
example: 
450% = 4.50
        
             
        
        
        
Answer:

Answer:
A function means that we get one input and one output.  In this example that means for every x-value that we have, we only have one y-value.
Looking at the first option, we can see that there is no x-value that has more than one y-value which means that it is a function.
The rest of the options are seen with at least two values for one x-value in one of the points.  Therefore, they wouldn't be considered a function leaving us with only option A as the solution.
