The fish weighs 184 ounces, and 11.5 pounds.
13kg is equivalent to 13,000g
First you would have to isolate y.
3x - 3y = 18 -----> Subtract 3x from both sides
-3y = -3x + 18 --------> Now divide both sides by -3
y= x - 6
Now you replace the y with an f(x)
f(x) = x - 6
That means our price markup is $67.00-$50.00=$17.00
Got me there but i think its 325500
