Dear Economic Analyst,
I need your expertise in determining how many workers to hire and how much feed to purchase. The current price of labor is $60 per day, and feed costs $75 per ton. Below is my marginal physical product of both labor and feed.
First, my current budget is unknown. Can you tell me the order in which I should purchase labor and feed? This order will provide priority when deciding on my level of inputs.
Secondly, although my budget is not completely known, I am guessing I will have around $480 to spend. If this amount becomes my true budget, what combination of labor and feed should I choose?
In your report, please give me all the data you are using for your analysis in a simple table. Clearly state how you are reaching your recommended decision.
Thank you in advance,
Donna Pigtail

PX1 = $60 per day
PX2 =$75 per day
The budget is: 60L + 75F = 480
It shall be noted that that level of X1 and X2 would be deployed, for which the MPP1/X1 = MPP2/X2
That is , the marginal physical product of labour per unit of labor is equal to marginal product of feed per unit of labor.

It shall be noted that MPP1/X1 is not equal to MPP2/X2 for given units of X1 and X2.
Thus, various combination of X1 and X2 should be discovered for which the budget is 480
It is X1 = 3 and X2 = 4 for which the Buget required is 480
MPP1/X1 at X1 = 3 is 2.7
MPP2/X2 at X2 = 4 is 2.90667
The firm should use 3 units of Labor and 4 units of Feed
