Nicole gave 12% of her collection of stamps to Abi thereby increasing Abi's collection by 20%. If Nicole had 44 stamps left, how many stamps did Abi have at first?
| |
Nicole's stamps |
Abi's stamps |
| Before |
100% |
100 u |
| Change |
- 12% |
+ 12% = + 20 u |
| After |
88% |
120 u |
88% of Nicole's collection = 44
1% of Nicole's collection = 44 ÷ 88 = 0.5
12% of Nicole's collection = 12 x 0.5 = 6
20 u of Abi's collection = 6
1 u of Abi's collection =
630 = 0.3
100 u of Abi's collection = 100 x 0.3 = 30
Answer(s): 30
