Let c=acres of corn planted and b=acres of beans planted. The farm has 70 acres altogether so\[b+c=70\]The farmer has $1800 to use to plant so the amount it costs to plant should be\[30b+60c \le1800\] The farmer has 120 days available for planting so\[4b+3c \le120\]Finally the farmer wants to maximize profit\[\max P=100b+180c\]
