$684 = 4(x + $19) is the equation.
To find the price of one ticket,
$684 = 4(x + $19) 
Divide each side by 4.
$171 = x + $19. 
Subtract $19 from each side. 
$152 = x.
The price of one ticket is $152
 
        
             
        
        
        
Last year total estimated cost: $2,265
This year (after 1 year) total estimates cost for 2 years is: 1.05 X $2,265 = $2,378.25
So, for 1 year will be the half of the above amount: $2,378.25 : 2 = $1,189.13
 
        
                    
             
        
        
        
Given the radius r and the tangent line AB, the length of the line OA is 24 units
<h3>How to determine the length OA?</h3>
The radius r and the tangent line AB meet at a right angle.
By Pythagoras theorem, we have:
AB² = OA² + r²
So, we have:
24² = OA² + 7²
Rewrite as:
OA² = 24² - 7²
Evaluate
OA² = 527
Take the square root of both sides
OA = 23
Hence, the length of OA is 24 units
