What does this meeting cost
Finance wants every meeting priced: length × attendees × hourly rate, rounded down.
- Cost = floor(minutes × attendees × ratePerHour / 60).
- Any zero input makes the cost zero.
meetingCost(minutes: int, attendees: int, ratePerHour: int) → int
Where you start
function meetingCost(minutes, attendees, ratePerHour) {
}Worked examples

meetingCost(0, 5, 100) | 0 |
Hint
Multiply first, then integer-divide by 60.
Reference solution in JavaScript
