Given :
A number 
.
To Find :
What is the sum of 12 1/4 and it’s additive inverse .
Solution :
Fist we should know what is additive inverse .
Additive inverse of a number is that number , when added to it yield zero ,
Basically , for a real number , it reverses its sign :
The opposite to a positive is negative .
The opposite to a negative is positive .
Therefore , the sum of 
and it's additive inverse is 0 .
Hence , this is the required solution .

Answer:
$28.82
Step-by-step explanation:
Since we are adding a 13% tax, we multiply 25.50 by 1 plus .13:
25.50(1 + 0.13)
25.50(1.013)
28.815
Alternatively, we could multiply 25.50 by 0.13 and then add the results:
25.50(0.13) = 3.315
25.50 + 3.315 = 28.815
