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
25 as many as Bryan.
Adam has 80 more than Charlie.
Let the number of stickers that Bryan has be 5 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 = 5 u
Number of stickers that Charlie has = 2 u
(b)
Number of stickers that Adam has = 2 u + 80
(c)
Total number of stickers
= 5 u + 2 u + 2 u + 80
= 9 u + 80
(d)
Number of stickers that Bryan has more than Adam
= 5 u - (2 u + 80)
= 5 u - 2 u - 80
= 3 u - 80
Answer(s): (a) 2 u; (b) 2 u + 80; (c) 9 u + 80; (d) 3 u - 80
