Bryan and Adam have some stickers.
15 of the stickers that Bryan has is 6 more than
12 of what Adam has.
Let
12 of Adam's stickers be 1 u.
- 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 = ___________
(a)
12 of Adam's stickers → 1 u
22 of Adam's stickers → 2 u
Number of Adam's stickers = 2 u
(b)
15 of Bryan's stickers → 1 u + 6
55 of Bryan's stickers → 5 x (1 u + 6) = 5 u + 30
Number of Bryan's stickers = 5 u + 30
(c)
Total number of stickers
= 2 u + 5 u + 30
= 7 u + 30
(d)
Difference in the number of stickers between Bryan and Adam
= (5 u + 30) - 2 u
= 5 u - 2 u + 30
= 3 u + 30
Answer(s): (a) 2 u; (b) 5 u + 30; (c) 7 u + 30; (d) 3 u + 30
