Adam and Bryan have some stickers.
13 of Adam's stickers is 8 less than
18 of Bryan's stickers.
Let
13 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)
13 of Adam's stickers = 1 u
33 of Adam's stickers = 3 u
(b)
18 of Bryan's stickers =
13 of Adam's stickers + 8
18 of Bryan's stickers = 1 u + 8
88 of Bryan's stickers = 8(1 u + 8) = 8 u + 64
(c)
Total number of stickers
= 3 u + 8 u + 64
= 11 u + 64
(d)
Difference in the number of stickers between Bryan and Adam
= 8 u + 64 - 3 u
= 8 u - 3 u + 64
= 5 u + 64
Answer(s): (a) 3 u; (b) 8 u + 64; (c) 11 u + 64; (d) 5 u + 64
