Adam and Bryan have some stickers.
13 of Adam's stickers is 11 less than
19 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)
19 of Bryan's stickers =
13 of Adam's stickers + 11
19 of Bryan's stickers = 1 u + 11
99 of Bryan's stickers = 9(1 u + 11) = 9 u + 99
(c)
Total number of stickers
= 3 u + 9 u + 99
= 12 u + 99
(d)
Difference in the number of stickers between Bryan and Adam
= 9 u + 99 - 3 u
= 9 u - 3 u + 99
= 6 u + 99
Answer(s): (a) 3 u; (b) 9 u + 99; (c) 12 u + 99; (d) 6 u + 99
