12 of Bryan's stickers is 8 more than
15 of Adam's stickers.
Let
15 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 Adam and Bryan = _____
(a)
15 of Adam's stickers = 1 u
55 of Adam's stickers = 5 u
Number of stickers that Adam has = 5 u
(b)
12 of Bryan's stickers =
15 of Adam's stickers + 8
12 of Bryan's stickers = 1 u + 8
22 of Bryan's stickers = 2(1 u + 8) = 2 u + 16
Number of stickers that Bryan has = 2 u + 16
(c)
Total number of stickers
= 5 u + 2 u + 16
= 7 u + 16
(d)
Difference in the number of stickers between Bryan and Adam
= 5 u - (2 u + 16)
= 3 u - 2 u - 16
= 3 u - 16
Answer(s): (a) 5 u; (b) 2 u + 16; (c) 7 u + 16; (d) 3 u - 16
