13 of Bryan's stickers is 4 more than
15 of Adam's stickers.
Let
15 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)
15 of Adam's stickers = 1 u
55 of Adam's stickers = 5 u
Number of stickers that Adam has = 5 u
(b)
13 of Bryan's stickers =
15 of Adam's stickers + 4
13 of Bryan's stickers = 1 u + 4
33 of Bryan's stickers = 3(1 u + 4) = 3 u + 12
Number of stickers that Bryan has = 3 u + 12
(c)
Total number of stickers
= 5 u + 3 u + 12
= 8 u + 12
(d)
Difference in the number of stickers between Bryan and Adam
= 5 u - (3 u + 12)
= 2 u - 3 u - 12
= 2 u - 12
Answer(s): (a) 5 u; (b) 3 u + 12; (c) 8 u + 12; (d) 2 u - 12
