Fill in the blanks in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Adam, Charlie and Bryan have some stickers.
Bryan has
49 as many as Adam.
Charlie has 100 less stickers than Bryan.
Let the number of stickers that Adam has be 9 u.
- Number of stickers that Bryan has = _____
- Number of stickers that Charlie has = _____
- Total number of stickers = _____
- Number of stickers that Adam has more than Charlie = _____
(a)
Let the number of stickers that Adam has = 9 u
Number of stickers that Bryan has = 4 u
(b)
Number of stickers that Charlie has = 4 u - 100
(c)
Total number of stickers
= 9 u + 4 u + 4 u - 100
= 17 u - 100
(d)
Number of stickers that Adam has more than Charlie
= 9 u - (4 u - 100)
= 9 u - 4 u + 100
= 5 u + 100
Answer(s): (a) 4 u; (b) 4 u - 100; (c) 17 u - 100; (d) 5 u + 100
