Can a discount make a busy business lose money?

A fictional lunch business charges ₹150, spends ₹90 per lunch and has ₹12,000 monthly fixed costs. It can make 300 lunches. Try a ₹120 price: how many lunches would cover the listed costs, and can the kitchen make that many?

Use the open calculator, keep a short recommendation in your own notes and return for the worked example. These figures are invented for practice.
