Fill in the blanks in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Charlie, Adam and Bryan have some stickers.
Bryan has
25 as many as Charlie.
Adam has 90 less stickers than Bryan.
Let the number of stickers that Charlie has be 5 u.
- Number of stickers that Bryan has = _____
- Number of stickers that Adam has = _____
- Total number of stickers = _____
- Number of stickers that Charlie has more than Adam = _____
(a)
Let the number of stickers that Charlie has = 5 u
Number of stickers that Bryan has = 2 u
(b)
Number of stickers that Adam has = 2 u - 90
(c)
Total number of stickers
= 5 u + 2 u + 2 u - 90
= 9 u - 90
(d)
Number of stickers that Charlie has more than Adam
= 5 u - (2 u - 90)
= 5 u - 2 u + 90
= 3 u + 90
Answer(s): (a) 2 u; (b) 2 u - 90; (c) 9 u - 90; (d) 3 u + 90
