Answer:
   x = 10
Step-by-step explanation:
The marked sides are proportional, so we have ...
   x/8 = (x +5)/12
   3x = 2(x +5) . . . . . multiply by 24 to clear fractions
   3x = 2x + 10 . . . . . eliminate parentheses
   x = 10 . . . . . . . . . . subtract 2x
_____
<em>Alternate solution</em>
We observe that the difference between the upper segment lengths is ...
   (x +5) -(x) = 5
and the difference between the lower segment lengths is ...
   12 -8 = 4
This means the upper segment lengths are 5/4 times as long as the lower segments. Then ...
   x = (5/4)(8) = 10
 
        
             
        
        
        
75 / 100 ( divided both numbers by 5 )
= 15 / 20 ( divided both numbers by 5 again )
= 3 / 4 Answer
        
                    
             
        
        
        
Answer:
C(t) = $28,000(0.811)^t  (Answer A)
Step-by-step explanation:
The value of the car is decreasing.  Thus, by the end of the first year of ownership, the car will have the value $28,000(1 -0.189)^1, where the "-0.189" represents DECAY instead of GROWTH.
Please use " ^ " to indicate exponentiation. 
Then the desired formula is C(t) = $28,000(0.811)^t  (Answer A)
