Marion gave 12% of her collection of cards to Xandra thereby increasing Xandra's collection by 24%. If Marion had 44 cards left, how many cards did Xandra have at first?
| |
Marion's cards |
Xandra's cards |
| Before |
100% |
100 u |
| Change |
- 12% |
+ 12% = + 24 u |
| After |
88% |
124 u |
88% of Marion's collection = 44
1% of Marion's collection = 44 ÷ 88 = 0.5
12% of Marion's collection = 12 x 0.5 = 6
24 u of Xandra's collection = 6
1 u of Xandra's collection =
625 = 0.25
100 u of Xandra's collection = 100 x 0.25 = 25
Answer(s): 25
