Answer:
$21,000
Step-by-step explanation:
This can be obtained by distributing the maximum allowed 15 gallons of pesticide into 6 gallons for 3 acres of Soybeans and 9 gallons also for 3 acres of corn.
With this, we will have:
P = (4000 * 3) + (3000 * 3) = $21,000
Note: See the attached excel file for the full calculation.
