Total number of stickers that Mary and Vanessa shared = 100%
If Mary gave 320 stickers to Vanessa, both would have the same number of stickers.
Number of stickers that each would have in the end
= 100% ÷ 2
= 50%
Number of stickers that Mary gave to Vanessa
= 82% - 50%
= 32%
32% → 320
1% → 320 ÷ 32 = 10
Number of stickers that Mary had
= 82%
= 82 x 10
= 820
Answer(s): 820
