120 of the stickers.
- 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 = ___________

120 =
1920 Number of stickers that Adam has = 19 u + 2
(c)
Total number of stickers = 20 u
(d)

= 19 u - 1 u + 2 + 2
= 18 u + 4
Answer(s): (a) 1 u - 2; (b) 19 u + 2; (c) 20 u; (d) 18 u + 4
