Fill in the blanks in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Bryan, Adam and Charlie have some stickers.
Charlie has
310 as many as Bryan.
Adam has 60 less stickers than Charlie.
Let the number of stickers that Bryan has be 10 u.
- Number of stickers that Charlie has = _____
- Number of stickers that Adam has = _____
- Total number of stickers = _____
- Number of stickers that Bryan has more than Adam = _____
(a)
Let the number of stickers that Bryan has = 10 u
Number of stickers that Charlie has = 3 u
(b)
Number of stickers that Adam has = 3 u - 60
(c)
Total number of stickers
= 10 u + 3 u + 3 u - 60
= 16 u - 60
(d)
Number of stickers that Bryan has more than Adam
= 10 u - (3 u - 60)
= 10 u - 3 u + 60
= 7 u + 60
Answer(s): (a) 3 u; (b) 3 u - 60; (c) 16 u - 60; (d) 7 u + 60
