Hilda had the same number of white, grey and red stickers at first.
Total number of stickers in the end
= 1 u + 4 u + 4 u - 23
= 9 u - 23
9 u - 23 = 238
9 u = 238 + 23
9 u = 261
1 u = 261 ÷ 9 = 29
Number of red stickers that Hilda had at first
= 4 u - 23 + 67
= 4 u + 44
= 4 x 29 + 44
= 160
Answer(s): 160
