- 5x5 =
- 25 u |
+ 5x5 =
+ 25 u |
| After |

110The number of coins that Pamela had at first is repeated. Make the number of coins that Pamela had at first the same. LCM of 10 and 8 is 40.
Number of coins that Vanessa had in the end
= 4 u + 25 u
= 29 u
Number of more coins that Vanessa had than Pamela in the end
= 29 u - 15 u
= 14 u
Number of more coins that Vanessa had than Pamela in the end in percent
=
1415 x 100%
≈ 93.3%
Answer(s): 93.3%
