Argument:

A year ago Apex Manufacturing bought its managers computers for their homes and paid for telephone connections so that they could access Apex computers and data files from home after normal business hours. Since last year, productivity at Apex has increased by 15%. Other companies can learn from the success at Apex: given home computers and access to company resources, employees will work additional hours at home and thereby increase company profits.

Issue:

Too many people think only about getting results. The key to success, however, is to focus on the specific task at hand and not to worry about results.

8           99,999²-1=? 10⁵(10⁵-1)

  如何做出来的啊？ 请NN指导一下。

     99,999²-1=（100，000-1）²-1=10⁵(10⁵-2)，不知对不对啊？

10. investment principal $6000, quarterly interests: 1Q $124; 2Q $135 3Q$141, what annual interest rate can make yearly interest 10%

3.5%, 9%, 10.% 10.5%, 12.5%

 no idea, please help?

=========================

my answer:

yearly interest is 10%, therefore, 124 + 135 + 141 + X = 6000 * 10% (X is the interests earned in 4th quarter)

so X = 200

the quarterly interest rate for 4th quarter is: 200 / (6000 + 124 + 135 + 141) = 200 / 6400 = 1 / 32 = 3.12%

so annual interest rate of 4th quarter is: 3.12% * 4 = 12.5%

Please correct me if i'm wrong. ;D
