Totally lost on how to use the Lagrangian method. Please solve using all steps and show all work, while clearly explaining what you're doing, so I can learn. Thank you.
Suppose you are running a factory producing anvils that requires steel as a raw material. Your costs are predominantly human labor (h), which is $20 per hour for your workers, and the steel itself (s), which runs for $160 per ton. Suppose your revenue is loosely modeled by the following equation: 100hs. If your budget is $10,000, how would you maximize revenue? Solve this problem using the Lagrangian method.
