13 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)
13 of Bryan's stickers =
17 of Adam's stickers + 7
13 of Bryan's stickers = 1 u + 7
33 of Bryan's stickers = 3(1 u + 7) = 3 u + 21
Number of stickers that Bryan has = 3 u + 21
(c)
Total number of stickers
= 7 u + 3 u + 21
= 10 u + 21
(d)
Difference in the number of stickers between Bryan and Adam
= 7 u - (3 u + 21)
= 4 u - 3 u - 21
= 4 u - 21
Answer(s): (a) 7 u; (b) 3 u + 21; (c) 10 u + 21; (d) 4 u - 21
