0.4% of $4,800 is $19.2, otherwise written as $19.20 in terms of money, apparently. This is based off the calculations of a calculator, though if you prefer to do the rough work, be my guest. The work for finding it on raw work is below.
(EX.) EQUATION : y = p% × x
EQUATION : y = 0.4% × 4800
To make this work, you gotta convert that percent into a decimal, by dividing the percentage by 100. 0.4 ÷ 100 = 0.004
EQUATION : y = 0.004 × 4800.
Once you multiply them, you get : 19.2 (otherwise known as $19.20)
        
             
        
        
        
4 big mice and 3 small mice because 4 X 25=100; 3 X 10=30
100+30=130
is that right?

The answer is a=6, b=4, and 0=3 you can always try to find the answer in google though 
Hope that helped
        
             
        
        
        
If we have 
y = 6x + 1 and x - y = 11, we can take advantage of  y - y = 0 as follows:
                                         Subtract x from both sides of the 2nd equation:
                                         -y = 11 - x
Now combine 
 y = 6x + 1
-y = 11 - x
--------------
0 = 5x + 12.  Solving for x, x = -12/5.     Using the equation above, find y:
                                                               -y = 11 - x
                                                                   = 11 - (-12/5)
                                                                   = 55/5 + 12/5 = 67/5
Then the solution is (-12.5, 67/5).
