- Number of stickers that Adam has = _____
(a)
Change information into units.
Bryan has four times as many as stickers as Charlie.
Number of stickers that Charlie has = 1 u
Number of stickers that Bryan has = 4 u
(b)
Adam + 1 u = 14 --- (1)
Adam + 4 u = 50 --- (2)
(2) - (1)
4 u - 1 u = 50 - 14
3 u = 36
1 u = 36 ÷ 3 = 12
(c)
Number of stickers that Adam has
= 14 - 1 u
= 14 - 12
= 2
Answer(s): (a) 4; (b) 12; (c) 2
