Answer:
D) 8
Step-by-step explanation:
3x - 7 - 2x + 5 = 6
3x - 2x  = 6 + 7 - 5
   x   = 8
Note: 6 + 7 -5 =  13 -5 = 8 
 
        
             
        
        
        
This is a quadratic formula with a general form of a²x + bx + c = 0. For quadratic equations, we can solve for its two roots using the quadratic formula shown in the attached picture.
a = -3
b = -4
c = -4
x = [-(-4) + √(-4)² - 4(-3)(-4)]/2(-3) = 
<em>2 + √-32/2</em>x = [-(-4) - √(-4)² - 4(-3)(-4)]/2(-3) =
<em> 2 - √-32/2</em>
 
        
        
        
Because when you divide you get the same answer or something to do with percents

Well what you would do is you would first subtract 45 from 325 (325-45) and that would become 280. Then you would divide that number by 8 (the cost of the T-shirt)(280/8) and then your answer would be 35. So the maximum number of T-shirts she will be able to buy is 38. Hope this will help you!
