题目一: 这题不懂题目到底要我求什麽，也完全无法列式
麻烦大家帮忙一下。
An investor buy one share of stock for 100.
If the share price change as follows
(measured relative to the prior day's price):
Day 1 Up 30%
Day 2 Down 15%
Day 3 Unchanged
Day 4 Chang r%
Day 5 Down 10%
If the pattern of relative price movements observed
on the first 5 days is repeated indefinitely,
how will the price of the share of stock behave in the long run?
题目二：麻烦大家告诉我，用什麽观念下去求比较快
A company has 120,000 to spend on the development and promotion
of a new product. The past experience indicates
that if x is spent on development and y is spent on promotion,
then X^(1/2)*Y^(3/2)/30,000*3^(3/2) items can be sold.
(a) To maximize the number of items sold,
how much money should be spend on development.
(b) What is the maximum number of items can be sold?
感谢各位的解答罗!!
