수학동아 - 폴리매스
함께 풀고 싶은 문제
나도 수학쌤 문장제 문제를 변형해 문제를 내는 곳입니다.
[문장제 문제&개념응용] [경우의 수] 6렙을 향해!

지금 나는 15000포인트(실제는 아니지만 비슷함)가 있다.
그럼, 6일 안에 안에 6렙을 가는(10000포인트를 추가로 모으는) 경우의 수는 얼마인가?
여기 표 참고:
| 할수 있는 일 |
한 번당 얻는 포인트 |
하루에 할수 있는 횟수 |
| 문제내기 |
300 |
5번 |
| 문제풀기 |
300 |
5번 |
| 주니어폴매 문제풀기 |
300 |
5일에 1번 |
| 폴매 문제풀기(부분해결) |
2000 |
5일에 1번 |
| 폴매 문제풀기(해결) |
10000 |
10일에 1번 |
| MVP선정 |
300 |
10일에 1번 |
| 로그인 |
100 |
1번 |
참고: 우리는 폴리매스 활동을 할려면 로그인을 해야 하지만, 이 문제에서는 로그인을 안 하고 다른 활동을 해도 됩니다.
또, 아무것도 안해도 됩니다. 예)폴매 문제 하나 풀고 5일동안 휴식가능
풀이 필수.이해가 안 가는거 있으면 댓글 달아주세요.
정답기준: 도나수 참고
