Number Plots

A farmer can plant up to 6 acres of land with soybeans and corn. Her use of a necessary pesticide is limited by federal regulations to 15 gallons for her entire 6 acres. Soybeans require 2 gallons of pesticide for every acre planted and corn requires 3 gallons per acre. The profit the farmer makes by earning $4,000 for every acre of soybeans he plants and $3,000 for every acre he plants with corn can be modeled by P=4000x+3000y . What is the maximum profit that she can earn?

• $15,000

• $21,000

• $18,000

• $25,000

• Their is no solution region therefore there is no maximum profit.

Based on the information choose all of the information that is true.
