Total number of cards that Wendy and Tiffany shared = 100%
If Wendy gave 180 cards to Tiffany, both would have the same number of cards.
Number of cards that each would have in the end
= 100% ÷ 2
= 50%
Number of cards that Wendy gave to Tiffany
= 86% - 50%
= 36%
36% → 180
1% → 180 ÷ 36 = 5
Number of cards that Wendy had
= 86%
= 86 x 5
= 430
Answer(s): 430
