Answer:
I would assume $10 is the cost of the booth and 5 is how much she earns for each T-Shirt, so the equation would be 5x-10=65. Assume $65 is what she earned.
Therefore, the equation may be: (your question did not specify) 5x-10=65. so x is 15. Therefore, she sold 15 T-Shirts.

In order to calculate the volume of a cylinder, we can use the following formula:

Where r is the base radius and h is the height.
If the circumference is 8, we have:

Now, calculating the volume, we have:

So the correct option is the second one.
 
        
             
        
        
        
0.69x+4.32=0.46x+3.4
              -3.4                   -3.4  
____________________
0.69x+0.92=0.46x
-0.69x           -0.69x
______________
0.92=-0.23
multiply by -100/23   multiply by -100/23

Step-by-step explanation:
count the slope, 5 up in 2.5 horizontal steps, slope = 5/2.5 or 2
x intercept is on the graph, 2.5
y intercept is also on the graph, -5
