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
38 as many as Bryan.
Adam has 90 more than Charlie.
Let the number of stickers that Bryan has be 8 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 = 8 u
Number of stickers that Charlie has = 3 u
(b)
Number of stickers that Adam has = 3 u + 90
(c)
Total number of stickers
= 8 u + 3 u + 3 u + 90
= 14 u + 90
(d)
Number of stickers that Bryan has more than Adam
= 8 u - (3 u + 90)
= 8 u - 3 u - 90
= 5 u - 90
Answer(s): (a) 3 u; (b) 3 u + 90; (c) 14 u + 90; (d) 5 u - 90
