Fill in the blanks in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Bryan, Charlie and Adam have some stickers.
Adam has
310 as many as Bryan.
Charlie has 40 more than Adam.
Let the number of stickers that Bryan has be 10 u.
- Number of stickers that Adam has = _____
- Number of stickers that Charlie has = _____
- Total number of stickers = _____
- Number of stickers that Bryan has more than Charlie = _____
(a)
Let the number of stickers that Bryan has = 10 u
Number of stickers that Adam has = 3 u
(b)
Number of stickers that Charlie has = 3 u + 40
(c)
Total number of stickers
= 10 u + 3 u + 3 u + 40
= 16 u + 40
(d)
Number of stickers that Bryan has more than Charlie
= 10 u - (3 u + 40)
= 10 u - 3 u - 40
= 7 u - 40
Answer(s): (a) 3 u; (b) 3 u + 40; (c) 16 u + 40; (d) 7 u - 40
