Answer: 119
Step-by-step explanation:
Let the acre of wheat to be cultivated be x.
Since the farm must grow three times as many acres of corn as wheat, therefore, corn = 3x
The information given can be used to form a equation as:
42(3x) + 30x = 18564
126x + 30x = 18564
156x = 18564
x = 18564/156
x = 119 acres of wheat
