18 of Bryan's stickers is 7 more than
19 of Adam's stickers.
Let
19 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)
19 of Adam's stickers = 1 u
99 of Adam's stickers = 9 u
Number of stickers that Adam has = 9 u
(b)
18 of Bryan's stickers =
19 of Adam's stickers + 7
18 of Bryan's stickers = 1 u + 7
88 of Bryan's stickers = 8(1 u + 7) = 8 u + 56
Number of stickers that Bryan has = 8 u + 56
(c)
Total number of stickers
= 9 u + 8 u + 56
= 17 u + 56
(d)
Difference in the number of stickers between Bryan and Adam
= 9 u - (8 u + 56)
= 1 u - 8 u - 56
= 1 u - 56
Answer(s): (a) 9 u; (b) 8 u + 56; (c) 17 u + 56; (d) 1 u - 56
