3 cousins share some stickers.
Adam has 50 more than Bryan.
Bryan has 2 times as many as Charlie.
Adam and Bryan have 800 more than Charlie.
- How many stickers does Bryan have?
- How many stickers does Adam have?
- How many stickers do Adam and Charlie have?
Choose the person with least stickers to be 1 u.
Number of stickers that Charlie has = 1 u
Number of stickers that Bryan has = 2 u
Number of stickers that Adam has = 2 u + 50
Number of stickers that Adam and Bryan have is 800 more than Charlie.
Number
of stickers that Adam and Bryan have = 1 u + 800 2 u + 50 + 2 u = 1 u + 800 4 u - 1 u = 800 - 50 3 u = 750
1 u = 750 ÷ 3 = 250 (a)
Number of stickers that Bryan has
= 2 x 250
= 500
(b)
Number of stickers that Adam has
= 2 u + 50
= 2 × 250 + 50
= 500 + 50
= 550
(c)
Number of stickers that Adam and Charlie have
= 2 u + 50 + 1 u
= 550 + 250
= 800
Answer(s): (a) 500; (b) 550; (c) 800
