Difference |
Before |
4x3 = 12 u |
9x3 = 27 u |
5x3 = 15 u |
Change |
- 7 u |
- 7 u |
|
After |
1x5 = 5 u |
4x5 = 20 u |
3x5 = 15 u |
Since Kimberly and Fanny shared the cost of their grandmother's present equally, the amount each paid for the present is the same.
So, the difference in the amounts between Kimberly and Fanny at first and in the end remains the same. Make the difference in the amounts between Kimberly and Fanny at first and in the end the same. LCM of 5 and 3 is 15.
Amount that Fanny spent on the present
= 27 u - 20 u
= 7 u
Percentage of her savings that Fanny spent
=
727 x 100%
≈ 25.9%
