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"
The correct solution is C
Subtract 6 from both sides of the equation
3x + 6 - 6 = 21 - 6
3x = 15
Then divide both sides by 3
x = 5
Subtract 6 from both sides of the equation
3x + 6 - 6 = 21 - 6
3x = 15
Then divide both sides by 3
x = 5
