Fill in the blanks in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Charlie, Bryan and Adam have some stickers.
Adam has
49 as many as Charlie.
Bryan has 40 more than Adam.
Let the number of stickers that Charlie has be 9 u.
- Number of stickers that Adam has = _____
- Number of stickers that Bryan has = _____
- Total number of stickers = _____
- Number of stickers that Charlie has more than Bryan = _____
(a)
Let the number of stickers that Charlie has = 9 u
Number of stickers that Adam has = 4 u
(b)
Number of stickers that Bryan has = 4 u + 40
(c)
Total number of stickers
= 9 u + 4 u + 4 u + 40
= 17 u + 40
(d)
Number of stickers that Charlie has more than Bryan
= 9 u - (4 u + 40)
= 9 u - 4 u - 40
= 5 u - 40
Answer(s): (a) 4 u; (b) 4 u + 40; (c) 17 u + 40; (d) 5 u - 40
