34The number of cards that Kimberly had at first is repeated. Make the number of cards that Kimberly had at first the same. LCM of 4 and 5 is 20.
Number of cards that Cathy had in the end
= 15 u + 8 u
= 23 u
Number of more cards that Cathy had than Kimberly in the end
= 23 u - 12 u
= 11 u
Number of more cards that Cathy had than Kimberly in the end in percent
=
1112 x 100%
≈ 91.7%
