[문장제 문제&개념응용] 이상한 여행 (최종)

이 이상한 여행을 끝내고 돌아온 아르, 키메, 데스는 공항에 도착했다. 공항에서 짐을 찾고 나와서 집으로 갈 교통수단을 고르는 세 친구는 버스와 지하철, 택시 셋 중 하나를 타기로 한다. 요금은 다음과 같다.
| |
택시 |
공항버스 |
지하철 |
| 요금 |
기본요금 3000원+1분당 100원 |
1인 6000원
(3명 23%할인)
|
1정거장마다 1000원, 환승시 750원 |
택시를 탈 경우, 최소 1시간 40분에서 최대 2시간이 걸리고, 지하철은 공항철도와 일반 지하철을 총 15정거장을 타게 된다. 이때 어떤 교통수단을 타야 가장 돈을 적게 내고 집에 올 수 있을까?
(단, 지하철은 공항철도가 6정거장 이상이며, 택시는 1시간 40분 59초까지 1시간 40분 요금)
버스가 이득인 경우, 택시가 이득인 경우, 지하철이 이득인 경우 다 써주셔야 하고, 시간이나 정류장의 개수 상관없이 성립하는 조건을 답해주셔야 합니다.
풀이 필수이고, 단문인경우 바로 내리겠습니다!
