Adam and Bryan have some stickers.
17 of Adam's stickers is 4 less than
19 of Bryan'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 Bryan and Adam = _____
(a)
17 of Adam's stickers = 1 u
77 of Adam's stickers = 7 u
(b)
19 of Bryan's stickers =
17 of Adam's stickers + 4
19 of Bryan's stickers = 1 u + 4
99 of Bryan's stickers = 9(1 u + 4) = 9 u + 36
(c)
Total number of stickers
= 7 u + 9 u + 36
= 16 u + 36
(d)
Difference in the number of stickers between Bryan and Adam
= 9 u + 36 - 7 u
= 9 u - 7 u + 36
= 2 u + 36
Answer(s): (a) 7 u; (b) 9 u + 36; (c) 16 u + 36; (d) 2 u + 36
