Choose the person who has less stickers to be 1 u.
Bryan has 5 less stickers than Adam.
So, Bryan has less stickers.
(a)
Number of stickers that Bryan has = 1 u
(b)
Number of stickers that Adam has = 1 u + 5
(c)
Total number of stickers
= 1 u + 1 u + 5
= 2 u + 5
(d)
Total number of stickers = 17
2 u + 5 = 17
2 u = 17 - 5 = 12
1 u = 12 ÷ 2 = 6
Answer(s): (a) 1 u; (b) 1 u + 5; (c) 2 u + 5; (d) 6
