17 of Bryan's stickers is 4 more than
18 of Adam's stickers.
Let
18 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)
18 of Adam's stickers = 1 u
88 of Adam's stickers = 8 u
Number of stickers that Adam has = 8 u
(b)
17 of Bryan's stickers =
18 of Adam's stickers + 4
17 of Bryan's stickers = 1 u + 4
77 of Bryan's stickers = 7(1 u + 4) = 7 u + 28
Number of stickers that Bryan has = 7 u + 28
(c)
Total number of stickers
= 8 u + 7 u + 28
= 15 u + 28
(d)
Difference in the number of stickers between Bryan and Adam
= 8 u - (7 u + 28)
= 1 u - 7 u - 28
= 1 u - 28
Answer(s): (a) 8 u; (b) 7 u + 28; (c) 15 u + 28; (d) 1 u - 28
