Based on the numbers provided, use excel to set up two diagrams (a.k.a.

Note that in both of these charts you should have the amount of labor on the horizontal axis.

Question

Let us take another look at the production grid from assignment No. 6:

	Capital
Labor	0	1	2	3	4	5	6	7	8	9
0	0	0	0	0	0	0	0	0	0	0
1	0	3	9	21	36	54	63	69	72	72
2	0	9	36	90	180	255	315	360	390	405
3	0	21	90	255	315	360	450	540	630	690
