Total number of cards that Tammy and Xandra shared = 100%
If Tammy gave 69 cards to Xandra, 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 Tammy gave to Xandra
= 73% - 50%
= 23%
23% → 69
1% → 69 ÷ 23 = 3
Number of cards that Tammy had
= 73%
= 73 x 3
= 219
Answer(s): 219
