___________________________________ 2) Sally buys a hand bag there was a discount of 30% if Sally paid $20 what was the original price
___________________________________ 3)Kelley wants Buy a magazine that it's $25 later the magazine was marked up an additional 20% what is the new price

Answer 1

I think you will have to divied 60 by 20 so it might be 30 dollars.
I think number 2 is 60 dollars.
Maybe it is 12 dollars and 50 cents.

Answer 2

1.) 60-(20% of 60)
60-(.2 * 60)
60-12
48
The pants are $48
2.)30% of x = 20
.3x = 20
.3x/.3= 20/.3
x = 66.6666666...
The pants were $66.67
3.) 25 + (20% of 25)
25+(.2*25)
25+5
30
The magazine is now $30.
