Answer:
x = (ab - ac )/c
Step-by-step explanation:
x/a = b/c - 1     Multiply through by ac:
cx = ab - ac     Divide both sides by c:
x = (ab - ac )/c.

The answer is $13.77
explanation is 67.45 - 18.78=48.67 and 100 - 48.67= $13.77
        
             
        
        
        
P=2L+2W
L=Length
W=Width
P=Perimeter=16
So you have:
16=2×5+2w 
Multiply 2 and 5 and get:
16=10+2w
Subtract 10 from both sides and get:
6=2w
Divide by 2 and get:
3=W
The width is 3.
