Rewrite using simple words: To determine the profit-maximizing output, we analyze the equilibrium point where marginal cost (MC) equals marginal revenue (MR), using current data from ticket sales and concessions. It is crucial to monitor MR as prices fluctuate; if MR exceeds MC, output should be increased, whereas if MR falls below MC, output should be decreased. An evaluation of the profit column reveals that maximum profits for large drinks, popcorn, and movies suggest an optimal output level that balances total revenue and costs effectively
