D because 1.29 plus 2.75 is 4.04(the money that he used to make the case) and subtract that with $12 and you get $7.96 as the profit.

Ok! I'll take you through this step by step!
First, we need to add up what it costs to make the case. So...
Needle/Thread: $2.75
Felt: $1.29
Now add them together... and... he spent... $4.04! 
Now he earned twelve dollars, so we have to subtract $4.04 from twelve to show his profits. 
    $12
-   $4.04
--------------
     $7.96
So his total profit was D.$7.96.
Hope this helps! Have a great day!
