Difference |
Before |
4x3 = 12 u |
9x3 = 27 u |
5x3 = 15 u |
Change |
- 2 u |
- 2 u |
|
After |
2x5 = 10 u |
5x5 = 25 u |
3x5 = 15 u |
Since Fanny and Lynn shared the cost of their cousin's present equally, the amount each paid for the present is the same.
So, the difference in the amounts between Fanny and Lynn at first and in the end remains the same. Make the difference in the amounts between Fanny and Lynn at first and in the end the same. LCM of 5 and 3 is 15.
Amount that Lynn spent on the present
= 27 u - 25 u
= 2 u
Percentage of her savings that Lynn spent
=
227 x 100%
≈ 7.4%
Answer(s): 7.4%
