Step-by-step explanation:
Area of circle formula:  r^2
r^2
r = 4,  = 3.14
 = 3.14
3.14 * (4^2) = 3.14 * 16 = 50.24
 
        
                    
             
        
        
        
Answer 
Find out the what was the price of the stereo .
To prove 
Let us assume that the price of the stereo be x .
As given 
Consumer Math The sales tax in the town where Amanda lives is 7%. 
7% is written in the decimal form 

= 0.07
As given
Amanda paid $35 in sales tax on a new stereo .
Than the equation becomes
x × 0.07 = 35 

solving the above
x = $ 500 
Therefore the price of the stereo is $ 500 .
Hence proved
 
        
             
        
        
        
Answer:
The first option.
Because we're solving for the price of each gallon, x will represent the cost of each gallon. Since 8.4 is the total amount of gallons, multiply 8.4 and x to get $23.94. Solve for x by dividing 23.94 to get $2.85 per gallon. To check this, substitute 2.85 for x into the equation: 8.4 (2.85) = 23.94
