Problem 19 of 7
A farmer plants x acres of corn and y acres of soybeans. They have at most 100 acres available. Corn requires 10 gallons of water per acre and soybeans require 8 gallons per acre. The farmer has at most 900 gallons of water. Write a system of inequalities for the constraints.
Using a hint is okay. It just tells the trainer to give you a little more review.

System must include two meaningful context constraints plus nonnegative restrictions.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Write one inequality for each resource or requirement.
2. Add nonnegative constraints for quantities that cannot be negative.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Single inequality when two constraints are required.
