The answer is 6. 8-6(6) = -28.

so.. as you can see, we use the decimal notation for the percentages... 65% is just 65/100 and 50% is just 50/100 and so on
so.. whatever the salted amounts are, we know they'll add up to (x+175)(0.50)
thus (0.30x) + (175)(0.65) = (x+175)(0.50)
solve for "x"
Use a box. Split the terms into the boxes and then multiply across. Sort of like area multiplication, only with terms.
3 5x
4y 12y 20xy
3 9 15x
