라임은 마트에서 물건을 정리하는 일을 하고 있다.
이 마트에서는 물건의 판매량, 즉 수익을 매우매우 중요시한다.
그래서 라임이 배치한 물건의 판매량이 높으면, 더 높은 시급을 받는다.
그러나, 이 물건을 정리하는데 너무 많은 시간을 쓰면, 시간당 정리량이 줄기에,
라임을 이를 잘 고려하여 최대의 돈을 얻어내야(?)한다.
라임은 4시간동안 일하고, 총 3개의 선반을 정리해야 한다.
각 선반에는 가치가 각각 절대 판매량이 1, 2, 3, ... 9인 9개의 물건이 오름차순으로 있고,
이 물건들의 상대 판매량은 거리와 절대 판매량의 곱으로, 거리는 주어진 그림과 같다.
거리 n을 움직일때 10n분의 시간이 걸린다고 하고, 시급은 20000+10*(증가한 상대 판매량)원 일때,
라임이 최대로 벌 수 있는 돈 m은 얼마인가?
