Калькулятор стоимости совещания/ отслеживание затрат в реальном времени

// Meeting cost calculation
function meetingCost({ participants, hourlyRate, durationMinutes }) {
  const hours = durationMinutes / 60;
  return participants * hourlyRate * hours;
}

// Annual salary → hourly rate
const annualToHourly = (annual) => annual / 2080;

// Example: 10-person, 1h meeting at $80/hr
meetingCost({ participants: 10, hourlyRate: 80, durationMinutes: 60 })
// → 800
