15 of Bryan's stickers is 7 more than
17 of Adam's stickers.
Let
17 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)
17 of Adam's stickers = 1 u
77 of Adam's stickers = 7 u
Number of stickers that Adam has = 7 u
(b)
15 of Bryan's stickers =
17 of Adam's stickers + 7
15 of Bryan's stickers = 1 u + 7
55 of Bryan's stickers = 5(1 u + 7) = 5 u + 35
Number of stickers that Bryan has = 5 u + 35
(c)
Total number of stickers
= 7 u + 5 u + 35
= 12 u + 35
(d)
Difference in the number of stickers between Bryan and Adam
= 7 u - (5 u + 35)
= 2 u - 5 u - 35
= 2 u - 35
Answer(s): (a) 7 u; (b) 5 u + 35; (c) 12 u + 35; (d) 2 u - 35
