Bryan and Adam have some stickers.
13 of the stickers that Bryan has is 5 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)
13 of Bryan's stickers → 1 u + 5
33 of Bryan's stickers → 3 x (1 u + 5) = 3 u + 15
Number of Bryan's stickers = 3 u + 15
(c)
Total number of stickers
= 2 u + 3 u + 15
= 5 u + 15
(d)
Difference in the number of stickers between Bryan and Adam
= (3 u + 15) - 2 u
= 3 u - 2 u + 15
= 1 u + 15
Answer(s): (a) 2 u; (b) 3 u + 15; (c) 5 u + 15; (d) 1 u + 15
