Total number of cards that Ivory and Yen shared = 100%
If Ivory gave 116 cards to Yen, 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 Ivory gave to Yen
= 79% - 50%
= 29%
29% → 116
1% → 116 ÷ 29 = 4
Number of cards that Ivory had
= 79%
= 79 x 4
= 316
Answer(s): 316
