I want you to modify the question to get a different answer. ex) (1) Her sale is increased by 5 percent in second half of 1998 from in the first half.

Their goal is to make u confuse.. My gooal is to make it clear.
9.
I like this problem because it combine several topics in a problem.
10.
MIxed with ratio problem.. Ususally do..
11.
Understanding Question
12.

13.
16% of population are employed females. So... 16/64=0.25
14.
(.15*500+x)/550 =.2

set up the variable with what you don't know. .0.7x=42
20.
How fast can u calculate it?
21.

22.
50% of x = .5x
23.
10% of 360
24.
The complaining comes from TeamB because people doesn't like it than A. Just 30% of 50...
25.

26.
guess what!
27.
I=0.25T, I_j=.45I, x=.45(.25T)
28.
.82t=138,, Get the approximation Understanding Question.
29.
m/(c+m) (1)m=.25c (2)c+m=250
30.

31.
no info for the total sale
32.
Ratio is the another expression of percentage
33.
Make an equation
34.
x(0.6T)>0.1T
35.

36.
x/(x+y)? so u need a relationship between x and y
37.
Organize the info Represent the question in math form.. 0.4f/(0.25m+0.4f)
