Answer:
$196
Step-by-step explanation:
Lets assume,
cost of a belt = 'x' 
cost of a pair of pants = 'y'
Now, According to the question;
- x + y = 490; 
- cost of a bag = twice the cost of belt = 2x;
- cost of a pair of pants = twice the cost of bag
     ⇒ y = 2×2x ⇔ 4x
hence, by subtituting the values in equation' we get;
 ⇒ x + 4x = 490
 ⇒ 5x = 490
 ⇒ x = 98
So, the difference between the cost of the pair of pants and the bag ;
⇒ y - 2x
⇒ 4x - 2x
⇒ 2x = 2×98 = 196. 
 
        
             
        
        
        
78 x 100 = 7800 
<span>How many times does 190 go into 780? </span>
<span>≈ 4....190 x 4 = 760 </span>
<span>780 - 760 = 20...bring down the extra 0 to make it 200. </span>
<span>How many times does 190 go into 200? </span>
<span>≈ 1...subtract 190 from 200 to get a remainder of 10 </span>
<span>190 ÷ 7800 ≈ 41</span>

I haven't done this kind of work in a bit, but I believe it's 8.
