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