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

= 3 u - 2 u - 15 - 15
= 1 u - 30
Answer(s): (a) 2 u + 15; (b) 3 u - 15; (c) 5 u; (d) 1 u - 30
