Fill in the blanks in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Charlie, Bryan and Adam have some stickers.
Adam has
57 as many as Charlie.
Bryan has 100 more than Adam.
Let the number of stickers that Charlie has be 7 u.
- Number of stickers that Adam has = _____
- Number of stickers that Bryan has = _____
- Total number of stickers = _____
- Number of stickers that Charlie has more than Bryan = _____
(a)
Let the number of stickers that Charlie has = 7 u
Number of stickers that Adam has = 5 u
(b)
Number of stickers that Bryan has = 5 u + 100
(c)
Total number of stickers
= 7 u + 5 u + 5 u + 100
= 17 u + 100
(d)
Number of stickers that Charlie has more than Bryan
= 7 u - (5 u + 100)
= 7 u - 5 u - 100
= 2 u - 100
Answer(s): (a) 5 u; (b) 5 u + 100; (c) 17 u + 100; (d) 2 u - 100
