Fill in the blanks in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Adam, Bryan and Charlie have some stickers.
Charlie has
710 as many as Adam.
Bryan has 100 less stickers than Charlie.
Let the number of stickers that Adam has be 10 u.
- Number of stickers that Charlie has = _____
- Number of stickers that Bryan has = _____
- Total number of stickers = _____
- Number of stickers that Adam has more than Bryan = _____
(a)
Let the number of stickers that Adam has = 10 u
Number of stickers that Charlie has = 7 u
(b)
Number of stickers that Bryan has = 7 u - 100
(c)
Total number of stickers
= 10 u + 7 u + 7 u - 100
= 24 u - 100
(d)
Number of stickers that Adam has more than Bryan
= 10 u - (7 u - 100)
= 10 u - 7 u + 100
= 3 u + 100
Answer(s): (a) 7 u; (b) 7 u - 100; (c) 24 u - 100; (d) 3 u + 100
