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 30 more 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 + 30
(c)
Total number of stickers
= 10 u + 7 u + 7 u + 30
= 24 u + 30
(d)
Number of stickers that Adam has more than Bryan
= 10 u - (7 u + 30)
= 10 u - 7 u - 30
= 3 u - 30
Answer(s): (a) 7 u; (b) 7 u + 30; (c) 24 u + 30; (d) 3 u - 30
