 Exercise FA3


1. For each of the production functions in Exercise FA2, find
mathematically where production is maximum. Do these correspond with
your graphs?

2. For prices of maize of $1,000 per Mg ($ is no particular
currency), N of $8 per kg and P205 of $10 per kg, find for what level
of phosphorus profit is maximized. Repeat for each level of N.
Discuss and interpret the results.

3. If you have time, you should repeat exercises FA1 to FA3 varying
nitrogen for each level of phosphorus.
