Bryan and Adam have some stickers.
18 of Bryan's stickers is 11 less than
19 of Adam's stickers.
Let
18 of Bryan's stickers be 1 u.
- Number of stickers that Bryan has = _____
- Number of stickers that Adam has = _____
- Total number of stickers = _____
- Difference in the number of stickers between Adam and Bryan = _____
(a)
18 of Bryan's stickers = 1 u
88 of Bryan's stickers = 8 u
(b)
19 of Adam's stickers =
18 of Bryan's stickers + 11
19 of Adam's stickers = 1 u + 11
99 of Adam's stickers = 9(1 u + 11) = 9 u + 99
(c)
Total number of stickers
= 8 u + 9 u + 99
= 17 u + 99
(d)
Difference in the number of stickers between Adam and Bryan
= 9 u + 99 - 8 u
= 9 u - 8 u + 99
= 1 u + 99
Answer(s): (a) 8 u; (b) 9 u + 99; (c) 17 u + 99; (d) 1 u + 99
