Adam and Bryan have some stickers.
16 of Adam's stickers is 3 less than
17 of Bryan's stickers.
Let
16 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)
16 of Adam's stickers = 1 u
66 of Adam's stickers = 6 u
(b)
17 of Bryan's stickers =
16 of Adam's stickers + 3
17 of Bryan's stickers = 1 u + 3
77 of Bryan's stickers = 7(1 u + 3) = 7 u + 21
(c)
Total number of stickers
= 6 u + 7 u + 21
= 13 u + 21
(d)
Difference in the number of stickers between Bryan and Adam
= 7 u + 21 - 6 u
= 7 u - 6 u + 21
= 1 u + 21
Answer(s): (a) 6 u; (b) 7 u + 21; (c) 13 u + 21; (d) 1 u + 21
