The blue group did because they ate 7 slices out of 8 while the green team only ate 2 out of 8
I think its like this
each row has 6 white tiles
8 rows = 48 tiles
48 - 6 = 42
42 x 8 = 336
so 8 rows = 6 white tiles and 42 purple tiles to make 48 tiles so she will need 336 more tiles to make each 8 rows have 48 tiles
hope this helps : )
