A fertilizer manufacturer has a new fertilizer it is testing to improve the
corn yield per acre (see data table). The experiment was performed with
equal area, water, corn type, and starting soil conditions for one growing
season. Group A was subjected to the new fertilizer and Group B was not
provided any fertilizer.
Based on the data, what is the optimal amount of new fertilizer to maximize com output?
6kgs per acre
sos per acre
10 kgs per acre
