Cindy gave 12% of her collection of stickers to Irene thereby increasing Irene's collection by 25%. If Cindy had 44 stickers left, how many stickers did Irene have at first?
|
Cindy's stickers |
Irene's stickers |
Before |
100% |
100 u |
Change |
- 12% |
+ 12% = + 25 u |
After |
88% |
125 u |
88% of Cindy's collection = 44
1% of Cindy's collection = 44 ÷ 88 = 0.5
12% of Cindy's collection = 12 x 0.5 = 6
25 u of Irene's collection = 6
1 u of Irene's collection =
624 = 0.24
100 u of Irene's collection = 100 x 0.24 = 24
Answer(s): 24
