- Number of stickers that Charlie has = _____
(a)
Change information into units.
Bryan has six times as many as stickers as Adam.
Number of stickers that Adam has = 1 u
Number of stickers that Bryan has = 6 u
(b)
Charlie + 1 u = 22 --- (1)
Charlie + 6 u = 37 --- (2)
(2) - (1)
6 u - 1 u = 37 - 22
5 u = 15
1 u = 15 ÷ 5 = 3
(c)
Number of stickers that Charlie has
= 22 - 1 u
= 22 - 3
= 19
Answer(s): (a) 6; (b) 3; (c) 19
