29 of the stickers.
- Number of stickers that Adam has = ___________
- Number of stickers that Bryan has = ___________
- Total number of stickers = ___________
- Difference in the number of stickers between Bryan and Adam = ___________

29 =
79 Number of stickers that Bryan has = 7 u + 12
(c)
Total number of stickers = 9 u
(d)
Difference in the number of stickers between Bryan and Adam
= (7 u + 12) - (2 u - 12)
= 7 u + 12 - 2 u + 12
= 7 u - 2 u + 12 + 12
= 5 u + 24
Answer(s): (a) 2 u - 12; (b) 7 u + 12; (c) 9 u; (d) 5 u + 24
