阿，明天就要去大阪了，今天做完也來不及問其他人，
所以來請各位戰友幫忙解惑! 謝謝!

of width r/2 feet. (其實我看不懂題目)

B: the area of the walk
Ans: B
2. Seven one-dollar bills are to be distributed amoung Lucia, Gomez, and
Domingo so that each person receives at least $1

one person receives at least $3
B: The total number of ways to distribute the bills.
Ans: C
3. 3<x<5

另外，我做PP3時發現我按"time"他不會顯示時間耶!!!
考試的時候她會自動出現到數的時間嗎?
還是我每按一次就顯示一次?
因為傻傻的以為PP3裡面只有兩組題目，居然拖到最後兩天做! 金喜a害~
先謝謝大家的解惑了!
