Assume Jerry sells x bags of dried turkey, and 2x bags of dried beef. He profits ($2)x on dried turkey, and ($1.5)(2x) on the dried beef. Therefore, his total profit is 2x + 3x = 5x. Since this is equivalent to $500, we can solve
5x = 500
x = 100
Therefore, Jerry must sell 100 bags of dried turkey and 200 bags of dried beef.
The unknown number is 1/2 or 0.5.
ex: 4x+6=8
Direct variation is y=kx and inverse variation is y=k/x, in this case:
y=-16/x
So this is an inverse variation with a constant of -16
