17 of Bryan's stickers is 2 more than
19 of Adam's stickers.
Let
19 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)
19 of Adam's stickers = 1 u
99 of Adam's stickers = 9 u
Number of stickers that Adam has = 9 u
(b)
17 of Bryan's stickers =
19 of Adam's stickers + 2
17 of Bryan's stickers = 1 u + 2
77 of Bryan's stickers = 7(1 u + 2) = 7 u + 14
Number of stickers that Bryan has = 7 u + 14
(c)
Total number of stickers
= 9 u + 7 u + 14
= 16 u + 14
(d)
Difference in the number of stickers between Bryan and Adam
= 9 u - (7 u + 14)
= 2 u - 7 u - 14
= 2 u - 14
Answer(s): (a) 9 u; (b) 7 u + 14; (c) 16 u + 14; (d) 2 u - 14
