Answer:
the equation to use would be D (255-20(5) = ?). To solve, first multiply 20 and 5 and you would get 100 so the equation would be 255 - 100 = ? Then you would subtract 100 from the 255 to get $155 left. To solve for 7 weeks you would replace the 5 in the equation with 7 so your equation would be 255 - 20(7) = ? Next you would multiply 20 and 7 to get 140. the equation would then be 255 - 140 = ? Subtract 140 from 255 and you would get 115. So after 7 weeks she would have $115 left in her account.
 
        
             
        
        
        
W>4.9 (NOTE: The greater than sign is supposed to be greater than OR equal to)
You can rewrite the inequality like this because you can simplify the equation to get rid of the 3.7. You do this by dividing both sides of the expression by 3.7, since that’s what the w is being multiplied by. 
Hope this helps!
        
             
        
        
        
Answer:
The assertion that g(f(x)) is continuous at c is true.
Step-by-step explanation:

 is continuous at c
 is continuous at c

 is continuous at
 is continuous at 
 which is defined as per given data thus g(f(x)) is continuous at x=c
 which is defined as per given data thus g(f(x)) is continuous at x=c
