Bryan and Adam have some stickers.
19 of Bryan's stickers is 5 less than
112 of Adam's stickers.
Let
19 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)
19 of Bryan's stickers = 1 u
99 of Bryan's stickers = 9 u
(b)
112 of Adam's stickers =
19 of Bryan's stickers + 5
112 of Adam's stickers = 1 u + 5
1212 of Adam's stickers = 12(1 u + 5) = 12 u + 60
(c)
Total number of stickers
= 9 u + 12 u + 60
= 21 u + 60
(d)
Difference in the number of stickers between Adam and Bryan
= 12 u + 60 - 9 u
= 12 u - 9 u + 60
= 3 u + 60
Answer(s): (a) 9 u; (b) 12 u + 60; (c) 21 u + 60; (d) 3 u + 60
