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
23 as many as Adam.
Charlie has 50 less stickers than Bryan.
Let the number of stickers that Adam has be 3 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 = 3 u
Number of stickers that Bryan has = 2 u
(b)
Number of stickers that Charlie has = 2 u - 50
(c)
Total number of stickers
= 3 u + 2 u + 2 u - 50
= 7 u - 50
(d)
Number of stickers that Adam has more than Charlie
= 3 u - (2 u - 50)
= 3 u - 2 u + 50
= 1 u + 50
Answer(s): (a) 2 u; (b) 2 u - 50; (c) 7 u - 50; (d) 1 u + 50
