Answer 1

Let the original salary be x
The first month:
0.8x
The second month:
(0.8)(1.2)x

(0.8)(1.2)x = 240
x = $250
So original salary is $250

Answer 2

From where did you get 0.8 and 1.2 ?

Answer 3

These can be confusing. think of it as S- 0.20 S
where S is the salary
this simplifies to 0.8S

Answer 4

similarly, a 20% raise is S+0.20S= 1.2S

Answer 5

0.8 is the cut of 20%, so 1-0.2 = 0.8
1.2 is the rise of 20%

Answer 6

Ohh! Okay. Thank you :)

Answer 7

I have one more question if you can please help me.. I'll post it now =)

Answer 8

Also, notice that a 20% cut followed by a 20% raise does not get you back to your original salary. That can be confusing!

Answer 9

Yeah! Well, the word problems in general are sooo confusing! And thanks :)
