Jeff knows that adding a special grain supplement to his cows will produce more milk according to the following schedule:

$\backslash (1/42/73/104/125/136/14\backslash )$

where the first number reports the total number of pounds of grain supplement, and the second number reports the total amount of milk produced. For example, $\backslash (4/12\backslash )$ means that if the cow is fed $4$ pounds of grain supplement, the cow will produce $12$ units of milk.

How many pounds of grain supplement should Jeff feed the cows if the farm receives $\backslash (\backslash$$ $0\mathrm{.}30\backslash )$ per unit of milk and the price of grain supplement is $\backslash (\backslash$$ $0\mathrm{.}80\backslash )$ per pound?

$3$ pounds

$2$ pounds

$1$ pound

$4$ pounds

Actually, Jeff should not even be in the business of farming.

$6$ pounds
