Total number of cards that Wendy and Elyse shared = 100%
If Wendy gave 145 cards to Elyse, 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 Elyse
= 79% - 50%
= 29%
29% → 145
1% → 145 ÷ 29 = 5
Number of cards that Wendy had
= 79%
= 79 x 5
= 395
Answer(s): 395
